->''Hi, and welcome to sort of a... musty episode of You Can't Do That on Television. The show that makes modern history every week by continually appalling its viewers.''
-->--'''Christine "Moose" [=McGlade=]''', the show's host from 1979 to 1986

Canadian SaturdayMorningKidsShow SketchComedy, running from 1979 to 1990, and rerun on and later produced by {{Nickelodeon}}. Heavily influenced by ''Series/RowanAndMartinsLaughIn'', borrowing modified and age-appropriate versions of several of ''Laugh-In'' sketches (most obviously, the joke wall, redesigned as a set of locker doors; the habit of dumping buckets of water and green slime on cast members, and the announcer) and catch phrases.

First introduced at CJOH Ottawa (a Creator/{{CTV}} affiliate) as a kids' variety show, the show's [[GermansLoveDavidHasselhoff wild success in America]] made it one of the defining shows of Creator/{{Nickelodeon}}'s history. It would run far longer on that network than it did in Canada, and the network's trademark green slime started with this show. The show's influence went beyond Nickelodeon, as homages have popped up everywhere from the sitcom ''Series/{{NewsRadio}}'' (in one episode, the cast was doused with buckets of green slime and water) to ''WesternAnimation/FamilyGuy'' (an episode in the 2011-12 season is titled "You Can't Do That On Television, Peter", and in another episode, Peter Griffin is himself slimed for saying "I don't know").

Brought CoveredInGunge to North America (and associated it with Nickelodeon). And Music/AlanisMorissette. No, really. The proof is [[http://www.ycdtotv.com/cast/cast.php?cmi=70 here]]. Also, the show was an early writing job for Bill Prady, who went on to create TheBigBangTheory.

In 2012, Creator/ShoutFactory released ''[[http://www.shoutfactory.com/?q=node/215640 You Can't Do That on Film]]'', a documentary about the history of the show.

Now with its own [[Radar/YouCantDoThatOnTelevision Getting Crap Past the Radar]] page.
----
!!This series provides examples of:
* AdultsAreUseless: Adults are usually portrayed as bumbling morons...at their ''best''. The one who isn't--Ross, the stage manager--is despicable for all other sorts of reasons. This was deliberate on the part of creator Roger Price, who hated that adults in kids' shows tended to be reliable, helpful, ReasonableAuthorityFigure[=s=] and wanted to teach kids that not all adults were like this.
* ArcadeSounds:
** Owing to the series' low budget, the machines in Blip's VideoArcade were just prop cabinets which used mechanical buzzers and bells to provide their sound effects, while the visual displays involved flashing lights behind coloured overlays.
** In a rare example of this trope being used correctly (owing to the year in which it was filmed), the 1982 episode "Addictions" features Christine playing the UsefulNotes/{{Atari 2600}} port of ''VideoGame/PacMan'' in many of the link segments, complete with appropriate sound effects (since she really is playing the game, not just waggling the joystick to a recording).
* TheBackstageSketch: The show showed the backstage area on occasion, but the best example of this from it is the introduction/theme elaboration sketches on the blue triangle set, which more often than not would lapse into being more about the making of said sketches.
* BadBoss: In the 1981 and 1982 seasons, Barth, proprietor of Barth's Burgery, had a not-too-bright teenage employee named Zilch (Darryl Lucas) whom he routinely belittled, insulted, and hit upside the head with a frying pan. All for minimum wage (at best).
-->'''Zilch:''' ''(entering while tying his apron)'' Good morning, Mr. Barth, sir!\\
'''Barth:''' Good morning, zit-face!\\
'''Zilch:''' Mr. Barth, give me ''one'' good reason why you can never say a kind word to me!\\
'''Barth:''' Because you are a wishy-washy, weak-kneed, acne-covered jellyfish!\\
'''Zilch:''' ''(glumly)'' ''One'' reason would do...
* BankruptcyBarrel: Ross and Moose end up wearing these during 1981's "Crimes & Vandalism", when their clothes (and most of the set) have been stolen. Moose's still has water and a rubber duck in it.
* BlandNameProduct: The series featured many commercial parodies (in fact, fake commercials were a regular part of the show during the 1982 episodes, which were originally aired before Nickelodeon became advertiser-supported); the objects of the parodies were often obvious, but the names were changed just enough to make them lawyer-friendly (for example, Head and Shoulders shampoo was parodied as "Shed and Holders", which cures Alasdair's dandruff by making his hair fall out).
* BrokenAesop: Several examples, usually in the form of HypocriticalHumor, in keeping with the series' deliberate subversion of the usual philosophy of children's television.
** There were a couple of these in the "Addictions" episode from 1982, notably a link set skit where Lisa reprimands Christine for being "addicted" to video games, but then it turns out Lisa has her own "unhealthy" addiction - to soap operas.
** In 1983's "Medicine", Senator Prevert (Les Lye) yells at Alasdair for having been caught smoking cigarettes in school, and then proceeds to light up a cigar.
--->'''Alasdair''': Wait a minute, I thought you just said smoking was bad for your health!\\
'''Sen. Prevert''': No no, I said, smoking is bad for ''your'' health. I never said anything about ''mine''.
* ButtMonkey: Zilch, Barth's (sub-)minimum wage employee in the 1981 and 1982 seasons, was constantly on the receiving end of slapstick abuse and degradation at Barth's hands, always PlayedForLaughs.
-->''(Zilch has been forced to dress as a clown to compete with [[BlandNameProduct McDoomland's and Burger Queen]])''\\
'''Barth:''' Hey, Zilch, c'mon! ''(honks a bicycle horn)'' You're supposed to be a clown! Make us laugh!\\
'''Zilch:''' ''(folds arms and scowls defiantly)'' If I'm going to be a clown, I want more ''money!''\\
''(Barth and the customers laugh uproariously)''
* TheCameo:
** The 1989 episode "First Times" and the 1990 episode "Privileges" both featured cameo appearances by 1981-84 cast member Kevin Kubusheskie (by then an associate producer for the series) and 1984-87 cast member Adam Reid (by then a writer for the series); in both episodes, they played upperclassmen being hazed by the regular cast members in opposite sketches set in the school corridor.
** The 1989 episode "Age", hosted by a returning Vanessa Lindores, features cameo appearances by four of the other more high profile cast members from 1979-87. Doug Ptolemy has a single line ("Hey Van, did you say my name?" after Vanessa comments that old ''YCDTOTV'' episodes with Doug will give her nightmares), while Christine [=McGlade=], Kevin Kubusheskie, and Alasdair Gillis make silent appearances in a post-credits classroom sketch (in which Mr. Schidtler growls, "Class dismissed - ''years ago!''").[[note]] Lisa Ruddy was slated to appear in the sketch as well but was out of town during filming.[[/note]]
* CanadaEh: The show is [[CanadianSeries a Canadian production]]. Other Canadianisms that found their way into the show: going "to university" instead of "to college",[[note]] while "university" means academic post-secondary education in Canada and the United States and "college" can refer to constituent parts of a university, "college" in Canada more usually refers to vocational institutions, while "college" in the United States more usually refers to undergraduate-only academic institutions[[/note]] and saying "grade ten" instead of "tenth grade." Although the writers did their best to [[CanadaDoesNotExist internationalize the show's content]] (very likely at Nickelodeon's insistence, since Nick and CJOH were production partners beginning with the 1982 season) by making references to American things such as the Fourth of July, it was little things like those in the script that (even without seeing the words "Ottawa, Canada" in the closing credits) made the show's country of origin obvious.
** More obvious in Season One and in ''Whatever Turns You On'' (which were never intended to be seen outside of Canada), with a number of jokes about one guy (Marc Baillon) being French, leading to the line "You don't speak Frog, eh?" ("Frog" is an offensive term for a French person [as in "from France" French], but can also be applied to someone from a French-speaking country -- in this case, Quebec.)
** In another scene, one girl (Cyndi) talked about her first crush being "a frog." Thinking Cyndi was using the offensive slang term, Christine scolded her. It turned out Cyndi was talking about an ACTUAL frog, which she then had to dissect for school, but didn't feel bad about it because she said, "Frogs aren't human." Upon hearing this, Marc came up and announced (referring to the Quebecois separatist movement), "Any more of that, and we WILL separate!"
* Along the same lines, the "internationalization" of the show's content after 1982 could be considered an example (though perhaps not an extreme one) of CanadaDoesNotExist, and the local 1979 and 1981 episodes as well as ''Whatever Turns You On'' could be considered an aversion of that trope - they were unapologetically Canadian, since the show's original raison d'etre was to improve the quality of CANADIAN kids' entertainment programming.
* CatchPhrase: And how. Some of the more repeated ones:
** Dungeon prisoners under the impression they are about to be freed always cheer, "Fresh air, blue skies, Barfy Burgers, ''girls!''"
** Barth's sketches often include a character quipping, "What do you think's ''in'' the burgers?" To which Barth invariably replies, "Duh... I ''heard'' that!"
** During arguments between two members of the Prevert family, a third family member often chimes in with, "She's got a point." To which the one without the point replies, "Don't encourage her."
** Mr. Schidtler reacts to smart-mouthed or dim-witted students by moaning, "Where do they find them, and why do they keep sending them to me?"
** When one of the performers outwits another (usually, but not always, a kid outwitting an adult), he or she tells the camera, "Sometimes it's so easy, I'm ashamed of myself."
** The execution scenes nearly always feature the following exchange between firing squad leader El Capitano and the intended victim:
--->'''El Capitano:''' Ready!... Aim!...\\
'''Kid:''' Wait a minute, stop the execution!\\
'''El Capitano:''' What is it ''this'' time!?\\
''(and, if the kid succeeds in tricking El Capitano into letting him/her go)''\\
'''El Capitano:''' That is one sneaky kid...
** Dungeon prisoners often tell dungeonkeeper Nasti, "But you can't do this, this is torture!" To which Nasti replies, "I know!"
** Ross, when conning the kids out of yet more money, has a favourite price of "Ten bucks. Each."
** Ross brings many episodes to an end by shouting, "Roll the closing credits!"
** The kids, upon realising that a given situation is too good to be true, will groan, "That means... this is JustTheIntroductionToTheOpposites!"
* ChristmasEpisode: The 1984 episode "Christmas" has Christmas-themed sketches, a running gag on the link set in which Alasdair is trying to get a kiss out of Christine, Lisa, and/or Vanessa by standing under the mistletoe,[[note]] All three finally kiss him in the episode's final scene, but make it very clear that it won't happen again.[[/note]] and a Christmas gift to Lisa's little brother: no locker jokes!
** ''Whatever Turns You On'' also did a Christmas episode five years earlier, which involved the kids trying to sneak into the network Christmas party, which they have been forbidden to attend because of the serving of alcohol. They end up singing Christmas carols on the link set and getting pied one by one by Les Lye's character Mr. Dime (dressed as Santa), as revenge for their giving ''him'' a pie in the face as a gift earlier in the show.
* CouchGag: Each episode is bookended by couch gags.
** Before the opening, a graphic announces that a regularly-scheduled show parody will not be seen tonight and will be replaced by an episode of ''You Can't Do That On Television''. The parodies being pre-empted always pertain in some way to the episode's main topic (e.g., ''Mr. Rogers: Neighborhood Pusher'' for "Drugs", ''George Bush Shoots the Wrong Quail'' for "Mistakes", ''The Huxtables Put Their Kids Up For Adoption'' for "Adoption", etc). In some instances, the show pre-empts ''itself''.
--->''You Can't Do That On Television'' cannot be shown at this time, because... we couldn't do it. In its place, we present a programme about television. ("Television", 1982)\\
The regular broadcast of ''You Can't Do That On Television'' will not be seen at this time, in order that the sponsors may bring you a new, improved, extra-strength, whiter than white, and extra clean programme! ("Media", 1983)\\
''You Can't Do That On Television'' will not be seen today, in order that we may get your priorities straight. Now turn off that television and go and do something constructive! ("Priorities", 1983)
** At the end of the closing credits, the announcer (played by Les Lye) declares, "''You Can't Do That On Television'' has been a (insert theme-relevant gag) Production". The camera then cuts to him as he makes a final gag about the show (which in itself could be an {{Homage}} to Gary Owens in ''Series/RowanAndMartinsLaughIn'').
* CoveredInGunge: Green slime, usually, though water was also common, as were cream pies. Covering the kids (and sometimes the adults) in gunge was one of the series' most familiar comedy devices.
* CreditsGag:
** The 1979 and 1981 series featured side comments in the credits, such as "Isn't this interesting?" and "This is like watching paint dry", and credited executive producer Bryn Matthews as "Executive Producer and Dragon Slayer" or similar titles.
** A number of episodes from the middle of the run featured the credit "Wardrobe courtesy Christine [=McGlade=] - Christine [=McGlade=] takes no responsibility for any clothes in which she appears".
** In the "Rip-offs" episode from 1982, Ross tries to run the closing credits immediately after Christine's introduction in a nod to the tendency of manufacturers to advertise a new, improved product that actually contains less content.[[note]] Christine stops the credits after a few seconds; they run in full at the end of the programme as Christine flees the collapsing link set.[[/note]]
** In "Priorities" from 1983, Ross runs the closing credits in the middle of the programme in an attempt to leave early for a baseball game.[[note]] This time, the credits do not run again at the end of the programme.[[/note]]
* CueCard: Several episodes feature link set segments in which we see Ross holding up cue cards containing Christine's lines (for example, in "Nutrition" from 1981, she refuses to read the card as written as she knows it will result on her getting milk dumped on her). In some cases, Christine is also shown holding cue cards containing Ross' lines, especially during scenes in which they are arguing about overreliance on cue cards.
* CurseCutShort: A common method of [[GettingCrapPastTheRadar Getting Crap (And Other Words Like It) Past the Radar]].
** From Episode 7 from the 1979 series:
--->'''Bradfield:''' Dad?\\
'''Sen. Prevert:''' Uh, yeah?\\
'''Bradfield:''' What's the definition of... "ignorance and apathy"?\\
'''Sen. Prevert:''' "Ignorance and apathy"? I don't know, and I don't give a sh- ''(catches himself)'' care.
** From "Safety First" (1981):
--->'''Angie:''' Hi, I'm Angie the Talking Doll!\\
'''Kevin Schenk:''' Angie, what can be done about juvenile crime? ''(pulls Angie's string)''\\
'''Angie:''' Invent an electric armchair, and ''burn'' the little-\\
''(cut to next scene)''
** From "Divorce" (1984):
--->'''Marjorie:''' ''(opens her locker)'' Hey, Alasdair?\\
'''Alasdair:''' ''(opens his locker)'' Yeah, Marjorie?\\
'''Marjorie:''' Do you ever worry about your parents getting a divorce?\\
'''Alasdair:''' Nah, not really.\\
'''Marjorie:''' Why not?\\
'''Alasdair:''' 'Cause I don't think they ever got married.\\
'''Marjorie:''' You mean that you're a-\\
''(Lisa, Christine, and Justin open their lockers)''\\
'''Alasdair, Christine, Justin, Lisa:''' ''Don't say it!''
* DeadpanSnarker: Moose, particularly during her link segments. Her favourite target for snarkery was, of course, the show itself.
-->'''Christine:''' ''(on the 1983 "Medicine" episode)'' Hi, and welcome to another painful episode of ''You Can't Do That On Television'', the show that has nothing to fear from infection, 'cause it couldn't get any sicker than it already is.
* DrivesLikeCrazy: Bus driver Snake Eyes (Les Lye). The school bus sketches nearly always ended with Snake Eyes seconds from crashing the bus into something or driving over a cliff.
* FinishDialogueInUnison:
** In the lead-in to the Opposite sketches, the characters gradually join in for a unison recital of "This is just the ''introduction to the Opposites.''"
** The Barth's sketches often end with a unison chorus from the customers of "[[IAteWhat What (or who) do you think's]] [[GrossOutShow in the burgers?]]" (To which Barth invariably replied, "Dahhh... I ''heard'' that!")
* FoodFight: A food fight breaks out in a Barth's sketch in "War" (1984), when Christine, Vanessa, Alasdair, and Adam Kalbfleisch determine that Barth would be willing to go to war for a situation he can no longer stomach... and since they can't stomach his food, they go to war over it.
* FunWithAcronyms: In the 1984 episode "War", Alasdair founds a peace movement called "War's Insane, Make Peace", or WIMP for short. Despite Adam Kalbfleisch's reservations about the name and Ross' constant mockery, Alasdair leads his followers to a peace rally, where the other peace groups beat them up for having such a silly acronym.
* FunWithSubtitles: The 1989 episode "First Times" features a link delivered in Japanese by Chris Bickford with English subtitles. When he reverts to English to protest to Ross, the subtitles remain.
-->'''Chris:''' Ross, this is stupid! ''(subtitle: Brilliant idea Ross.)'' ''(Chris notices the subtitle)'' Wait... I didn't say that! Ross!\\
'''Ross:''' The subtitle is right! ''You'' are wrong.\\
'''Chris:''' But Ross!... ''(subtitle: I don't know!)'' ''(Chris gets slimed)'' Th... that's not fair! I didn't even say 'I don't know!' ''(Chris gets slimed again)''\\
'''Ross:''' But it did on the subtitles. ''(chuckles)''
* GenreSavvy: By the 1982 series, the cast were smart enough to know what would happen if they said "I don't know" or "water" and would try to find ways to sidestep having to use those phrases. They would still slip up at least once an episode, though, and their attempts to dodge slime and water with alternate phrases were not always successful (see TheScottishTrope for several examples).
* GreasySpoon: Barth's Burgery, decorated in an unappetizing shade of green and serving nothing that wouldn't make patrons sick.
* HoistByHisOwnPetard:
** Many characters were slimed or soaked when they tried to trick other characters into saying "I don't know" or "Water" and ended up saying the magic words themselves first. For example, "Jealousy" from 1984 features this exchange:
--->'''Marjorie:''' Hey Christine, aren't you a little jealous of your parents because they can drink liquor and you can't?\\
'''Christine:''' No.\\
'''Marjorie:''' Oh, come on now. You're drinking milk, and they're having scotch and... ''and''...\\
'''Christine:''' ... soda?\\
'''Marjorie:''' No, you idiot, you were supposed to say "water"! ''(gets drenched)''\\
'''Christine:''' Sorry Marjorie, my parents don't drink!
** In the 1984 "Technology" episode, the "interactive gizmo" that claims to allow viewers to vote on how a sketch proceeds by pressing a green or red square on the television screen is used for two "tests" that both fall under this.
*** Luke [=McKeehan=], facing execution by El Capitano's firing squad, persuades a sceptical El Capitano to let the viewers decide if he should be shot. The "results" are 9999 votes for, 2002 votes against, and the sketch closes with Luke trying to argue for a computer error as El Capitano shouts, "Ready!... Aim!..."
*** In the very next sketch, Vanessa is chained up in Nasti's dungeon, and he is planning to drop green slime on her. Vanessa tries to get out of a sliming by asking Nasti to let the viewers decide; however, he makes a point of presenting sliming as great fun to influence the vote, and the "results" are 9999 votes for, 35 votes against. A resigned Vanessa triggers the slime by answering "I don't know" to Nasti's question, "What is green slime made of?"
** Played with somewhat in the 1987 "Books and Reading" episode. Stephanie Chow asks Matthew Godfrey about mirages in the desert in an attempt to get him to say "Water," but he doesn't cave. Then Matthew says "Water" and gets drenched anyway while explaining Stephanie's trick to Adam Reid afterward.
* HypocriticalHumor: As with many children's comedies, much humour was derived from the characters denouncing the very things they were doing. For example, in the "Addictions" episode from 1982, Christine scoffs that, unlike adults, kids are not prone to addictive behaviour... all while she is unable to tear herself away from ''VideoGame/PacMan'', Kevin Kubusheskie is buried in an issue of ''Motor Trend'', Martin Kerr is obsessing over a Rubik's Cube, and Lisa is immersed in a pulp romance novel.
* IAteWhat:
** Most of the Barth sketches involve disgusting revelations about what goes into the burgers the kids are halfway through eating (mouse heads and tails, used kitty litter, maggots, dead human bodies, etc.).
--->'''Barth''': Duuuuuuh...I ''heard'' that!
** The 1989 episode "Mistakes" features a breakfast sketch in which Mr. Prevert is drinking what he thinks is the last glass of apple juice. Chris, disgusted at missing out on the juice, gets up to leave for a doctor's appointment, and Mrs. Prevert tells him that his urine sample is in an old apple juice container. Cue massive SpitTake from Mr. Prevert...
** In an early 1979 episode, one of the boys begins eagerly tucking into a plate of caviar (at first mistaking it for strawberry jam), then, when Christine tells him what's in it ("Jim, that's fish eggs, y'know, like FROG SPAWN"), runs off the link set to puke.
** In the 1989 "Celebrations" episode, the kids are eating haggis (sheep's intestines cooked in a sheep's stomach) to salute Scotland - and enjoying it. Of course, this is the introduction to the opposites... when the opposites are over, the kids are grossed out, Amy Stanley asks for a drink to get the taste out of her mouth, and you know what happens when you mention dihydrogen monoxide on this show...
** Stephanie Bauder encountered an unfortunate real life example of this when filming a dining room scene and accidentally taking bites of food Les Lye had spat out on a previous take.
* ICantBelieveItsNotHeroin: Invoked with cream pies in the episode "Drugs", the pies have this effect ''specifically because'' they're stand-ins for heavy drugs.
* IncrediblyConspicuousDrag: Les Lye on a number of occasions, including the Unfairy Godmother in 1982's "Not-So-Fair Show," Barth's mother in "Relatives" (1985), and another fairy godmother (Pinocchio's) in "Fairy Tales, Myths and Legends" (1986). Averted/played with in the 1979 season with the character of Frederick, the flamboyant gay-stereotype wardrobe master.
* IronicEcho: From 1981's "Crimes & Vandalism":
-->'''Mr. Schidtler:''' Hey! ''(thwacks his cane against his desk to silence his rowdy class)'' Vandals broke into the school office last night and stole all this year's examination papers. I'm afraid, kids, you're not going to be able to write this year's examinations. ''(the kids begin cheering)''\\
'''Kevin Schenk:''' ''(sarcastically)'' Too bad, sir. What a pity, sir. I'm heartbroken, sir, I really am.\\
'''Mr. Schidtler:''' ''(holding a sheaf of paper)'' So instead, you are going to write next year's examination... now.\\
'''Kevin Schenk:''' ''Next year's exam!?'' We'll all fail!\\
'''[[SadistTeacher Mr. Schidtler]]:''' ''(smirks)'' Mmm. Too bad. What a pity. I'm heartbroken. I really am.
** The 1985 "Revenge" episode featured Alasdair Gillis making everyones' lives miserable as the "Masked Revenger." After Mr. Schidtler apprehends the Masked Revenger for stealing the class's milk-fund money (ostensibly so he could buy a pair of pants and wouldn't be teased for wearing tights anymore), he echoes the Revenger's catchphrase, "My work here is done," as he hauls the Revenger off to the principal's office while the rest of the class applauds.
* IsThisThingStillOn: After the end credits, the announcer would always make some sarcastic remark about the show, oblivious to the blinking red "On Air" light behind him until an off-screen crew member silently pointed out that they were still live, at which point he would turn to the camera with a [[OhCrap deer-in-headlights look]].
* JackassGenie: "My work here is done." The writers loved malevolent or incompetent genies as comedy devices, and at least three fall squarely into the Jackass Genie category of deliberate wish-mangling:
** "The Not-So-Fair Show" (1982) features Les Lye as the [[IncrediblyConspicuousDrag cigar-smoking, deep-voiced]] "Unfairy Godmother".
--->'''Christine''': I said I wish I was thinner.\\
'''Unfairy Godmother''': Thinner! And so - you - shall - be! ''(transforms Christine into a can of paint thinner)'' Ha ha! The Unfairy Godmother strikes again!
** "TV Commercials" (1986) has Doug Ptolemy as the "Jiffy Genie".
--->'''Mrs. Prevert''': Oh Jiffy Genie, can you get rid of all this oven grease?\\
'''Jiffy Genie''': In a flash, ma'am. ''(waves his arms, and Mrs. Prevert's entire oven disappears. Mrs. Prevert wails and begins to sob loudly)''\\
'''Announcer''': Yes, with Jiffy Genie, you'll never have oven grease again.\\
'''Jiffy Genie''': ''(to camera)'' You'll never have an oven, period. ''(Mrs. Prevert begins wringing the Jiffy Genie's neck)''
** In "Fitness" (1989), Ted Wilson as the "Fitness Genie" ("Fitness Genie is the name, helping fatsos is my aim!") grants Rekha's wish to lose more weight by making her fatter (giving her more weight to lose), then makes her "lighter" by first making her glow like a lightbulb and then making her float away.
* {{Jerkass}}: Moose. The director even more so.
* JustTheIntroductionToTheOpposites: The TropeNamer. Every episode features a short series of sketches, collectively known as "The Opposites", in which roles are reversed, the adults encourage bad behaviour and discourage good behaviour (over the kids' protests), and the kids greet punishments with enthusiasm and rewards with disgust.
* LamePunReaction: Part of the series' self-deprecating humour; for every bad pun used in the jokes (and there are many), there is a cast member groaning at it.
-->'''Lisa:''' ''(talking to a sleeping bag)'' Look, look, there are a lot of worse things you could be than a sleeping bag! I mean, you could be a pillow, or even a pincushion!\\
'''Alasdair:''' ''(entering the bedroom)'' Uh, Lisa, what are you doing?\\
'''Lisa:''' Well... trying to cheer up the sleeping bag.\\
'''Alasdair:''' Why would you want to cheer up a sleeping bag?\\
'''Lisa:''' Well, 'cause my dad says it's a ''down'' sleeping bag.\\
'''Alasdair:''' A ''down'' sleeping bag, Lisa!? You need help. ''(starts to make a hasty exit)'' A lot of help!\\
''(cut to Christine on the link set)''\\
'''Christine:''' ''(disgusted)'' "Down". Boy, is that ever ''bad!'' [[WhoWritesThisCrap You know, whoever writes this stuff really needs a holiday.]]
* LessEmbarrassingTerm: This exchange between Elizabeth Richardson and Kevin Kubusheskie from "Cosmetics" (1982):
-->'''Elizabeth:''' ''(sniffs Kevin)'' Gee, that's nice perfume you're wearing!\\
'''Kevin:''' Boys don't wear perfume!\\
'''Elizabeth:''' ''(sniffs again)'' Then what makes you smell so nice?\\
'''Kevin:''' Oh, that's my new aftershave.\\
'''Elizabeth:''' You mean, you shave?\\
'''Kevin:''' Well, no, not exactly...\\
'''Elizabeth:''' Like I said: that's nice perfume you're wearing.
* LethalChef:
** Barth, unabashedly. He puts almost anything in his burgers except ground beef, and no food is too old to serve. Yet for some reason the kids keep eating at his diner.
--->''(when the kids complain that the burgers he serves look nothing like the picture advertising his food)'' "I'll have you know that is the exact same burger that we took the picture of, ''six months ago''."
** Mrs. Prevert is a downplayed example. She can cook, but the only dish she knows how to make is liver and lima beans.
* LetsSeeYOUDoBetter: In a meta example, Adam Reid was invited to audition for the series after writing in to criticise the acting by the child performers. He was immediately cast as a regular performer, and went on to write for the series in its final two seasons.
* LiteralGenie: As mentioned in JackassGenie, the writers loved malicious or inept genies as comedy devices. At least two fell into the Literal Genie flavour of accidental wish-bungling:
** "ESP, Magic, and Astrology" (1984) features Les Lye as the "Genie of the Electric Lamp", who grants Christine's wish never to do housework again by making her entire house disappear, then grants Kyle and Korbett's wish to be on the winning team by giving them the uniforms of their opponents.
** "Revenge" (1985) stars Alasdair Gillis as the "Masked Revenger", a genie-like "superhero" who grants wishes for revenge.
--->'''Masked Revenger:''' ''(enters accompanied by heroic theme music)'' I am the Masked Revenger. Against whom do you seek revenge?\\
'''Marjorie:''' My mother. She promised to make me fried chicken tonight, and she lied.\\
'''Masked Revenger:''' Say no more, little one. ''(transforms Marjorie into a bucket of fried chicken)'' My work here is done. ''(flies off as the bucket of fried chicken clucks angrily)''
** The "Jiffy Genie" skits in the "TV Commercials" episode (see JackassGenie above) also fall into this category. In addition to tormenting Mrs. Prevert, the Jiffy Genie also comes up with a foolproof way for Alasdair to hide a zit - by shoving a toilet plunger into Alasdair's face.
--->'''Announcer:''' Jiffy Genie hides all zits from your girlfriend!\\
'''Jiffy Genie:''' Actually, it hides your entire face from her too. In Alasdair's case, she should be grateful.
* LoadsAndLoadsOfRoles:
** Les Lye played all the adult male characters (stage manager Ross Ewich, slobbish Senator and father Lance Prevert, LethalChef Barth, greedy arcade owner Blip, SadistTeacher Mr. Schidtler, etc.), sporting enough distinct looks that this fact wasn't immediately obvious (though Lance Pervert and Barth do sound alike).
** From 1982 onwards, the adult female roles (Valerie Prevert [wife of Lance Prevert], the English-accented librarian, the doctor's assistant, etc.) were all played by Abby Hagyard.
** For 1979's ''Whatever Turns You On'', CTV provided CJOH with a bigger budget, and so they were able to hire RuthBuzzi to play the adult female roles. Previously on YCDTOTV, adult female roles had been played by one of the older girls in the cast; in the 1981 season, all adult female roles were played by Christine.
* MirrorCrackingUgly: Les Lye's Senator Prevert and Barth characters.
* MotorMouth: Lisa Ruddy
* NoFourthWall: The show knows it's a show and the characters constantly interact with the "director". An episode about divorce had the show being interrupted because the producer and his wife split up and was collecting the half she got in the settlement.
* TheNotSoHarmlessPunishment: One sketch had a child being 'grounded' and having his shoes taken away. The kid points out that having his shoes taken away won't stop him leaving the house. The adult then says that the child has misunderstood. Now that he has taken off his rubber-soled shoes, he is 'grounded' and hands the kid a live electric cable...
* [[OnlySaneMan Only Sane Kid]]: Moose, in a capacity similar to that of Kermit the Frog on the ''Series/TheMuppetShow''.
* OneSteveLimit: Inevitably for such a long-running series with such a high cast turnover rate, there were many performers with the same first name, and in some cases their tenures on the programme overlapped. Just to name two examples:
** The 1979 episodes featured Kevin Schenk and Kevin Somers, and in their last series in 1981 they were joined by Kevin Kubusheskie (though no episodes featured all three together), while Kevin Kubusheskie had several cameos in episodes featuring 1989-90 cast member (and writer) Kevin Ward.
** The 1985 and 1986 series featured appearances by Adam Kalbfleisch and Adam Reid (though never in the same episode).
* OverlyLongGag: In "Ripoffs" from 1982, a classroom sketch features Alasdair unwrapping a chocolate bar. There are so many layers of wrapping that we cut away to other sketches ''three times'' (including, in the original broadcast, the "Let's talk to some kids" interview sequence) before finally reaching the payoff, in which Alasdair finally gets to the disappointingly small chocolate and notes that companies advertising "more (product)" almost invariably deliver less.
* ParodyCommercial: The 1982 series featured parody commercials before cutting to actual commercials.[[note]] As mentioned under EditedForSyndication, when Nickelodeon became ad-supported in 1983, they were the first sketches to be cut from re-runs.[[/note]] Just to name a few:
** "Ripoffs" had an ad for the "Wimpex Watch", in which Alasdair's watch is still ticking even after being beaten up by Brodie and Kevin Kubusheskie.
** "Sports" featured a spoof ad for "Hockey Pro Toothpaste", a toothpaste intended to give the user the "missing tooth" look of professional hockey players.
** "Heroes" promoted "Hero Cereal", the cereal that goes "[[WrittenSoundEffect Slam! Bam! Crunch! Whack!]]" when Doug pours milk on it (the "Whack!" coming from Mr. Prevert smacking him upside the head for eating such a noisy breakfast).
** "The Not-So-Fair Show" had Doug modelling the "Lotachi Lugman", a personal stereo with full-size speakers for headphones.
* ParodyNames: In parallel with BlandNameProduct, other television programmes were sometimes referenced in the series using parody names. Curiously, the 1982 "Addictions" episode featured a parody name and an actual reference to the same series; in a dining room sketch, Luke [=McKeehan=] finds a plush [[Franchise/TheSmurfs Smurf]] doll in a cereal box and declares, "There's a free Slurp in the [[BlandNameProduct Cannon Crunch]] cereal!", but in the post-credits stinger, Christine talks about a video game cartridge that allows viewers to "shoot down all those stupid little Smurfs".
* PieInTheFace: Not as ubiquitous as the green slime, but it popped up on a number of occasions. One episode (1981's "Drugs") was even built around the gag, equating the stupidity of hitting yourself with a pie to the stupidity of harming yourself by taking drugs.
* PunnyName:
** Stage manager Ross' full name is Ross Ewich (try saying it fast).
** Several episodes feature a producer whose name appears on his chair as "[[GettingCrapPastTheRadar R. Sole]]" (again, try saying it fast). In the 1981 episode "Safety First", Christine even remarks that [[LampshadeHanging if she had a name like that, she wouldn't put it on the back of her chair]].
* ReunionShow: The second [=SlimeCon=] cast reunion in 2004 included the special episode "Project 131", featuring the now grown Brodie Osome, Vanessa Lindores, and Marjorie Silcoff re-visiting the old ''YCDTOTV'' studio following Ross' retirement to film one final episode. The classic sets were recreated with green screen technology, a final sliming and drenching were delivered (to Brodie and Marjorie, respectively), and the final scene featured brief appearances by Alasdair Gillis and Justin Cammy. Les Lye's grandson, Josh Dunn, appeared as the announcer.[[note]] Following this episode, Studio D at CJOH, in which the series had been recorded, was closed permanently, ending the possibility of further reunion shows.[[/note]]
* RougeAnglesOfSatin: In the classroom sketches, almost every word that appears on Mr. Schidtler's blackboard is misspelled. Although most of the misspellings are not actual words (for example, "basex" for "basics"), occasionally they fall under this trope. For example, in "The Not-So-Fair Show" (1982), Mr. Schidtler quotes Act I, Scene 1 of ''Theatre/{{Macbeth}}'' with "Fare is fowl, fowl is fare" instead of "Fair is foul, foul is fair".
* SadistTeacher: The teacher in the classroom sketches, Mr. A. Schidtler, looked like Adolf Hitler and had a personality to match. Although he often bewailed the constant parade of dim-witted and/or smart-mouthed students in his classroom, he also delighted in making their lives miserable with huge volumes of homework and other forms of torment.
-->'''Mr. Schidtler:''' Now, class, as we are going on a field trip, I think it is most important that we know the basics of nature. Can anyone tell me, what are the four natural elements of the universe? ''(Lisa raises her hand)'' Yes, Lisa.\\
'''Lisa:''' Earth.\\
'''Mr. Schidtler:''' Right! That's one. Umm... Kevin!\\
'''Kevin Kubusheskie:''' ''(lifting his head off his desk)'' Uh... air!\\
'''Mr. Schidtler:''' Yeah, that's right, that's two... Christine?\\
'''Christine:''' ''(lifting her head off her desk)'' Uh... fire!\\
'''Mr. Schidtler:''' That's right! And now... Vanessa. Can you tell me what the fourth element is?\\
'''Vanessa:''' Yeah. But I'm not going to.\\
'''Mr. Schidtler:''' Well, Vanessa... either you tell me what the fourth element is, or you tell me you don't know.\\
'''Vanessa:''' Well, either way I get something dumped on me. ''(gives in)'' Okay, water. ''(water falls on her)''\\
'''Mr. Schidtler:''' ''(grinning)'' Ohh, it's moments like these that make teaching worthwhile!
* SchmuckBait[=/=]TheScottishTrope: The characters were soaked with water when they said "water" (or, during the early seasons, "wet") or slime when they said "I don't know". As the series' most familiar comic device, this was played with several times:
** In the 1982 episode "Fads & Fashions", Christine, having subscribed to a fashion trend of wearing scuba gear, tried unsuccessfully to trigger a water drop by saying "water". Apparently, it only falls if the kids aren't expecting it.
** In an opposite sketch in the 1982 episode "Heroes", saying "I know" triggered the slime... to the amazement of several kids who said "I don't know" and avoided the slime. Another episode reversed this, where a character during the opposited muttered "I don't know", said to stop the slime because of the opposites meant that he does know, only to be told that the opposites are over.
** "The Not-So-Fair Show" from 1982 had Christine get water dumped on her for saying "Eau de cologne". An amused Alasdair explained that "'eau' is the French word for 'water'"... and got drenched himself.
** Also from "The Not-So-Fair Show", the Unfairy Godmother slimed all of the kids except Christine for saying "We know".
** In the 1983 episode "Future World", Christine tried to avoid a sliming by saying, "Insufficient data." Following the sliming, Lisa said that the slime dispenser was now computer-controlled.
** In the 1984 episode "Hobbies", Christine said "Oh no you don't!" when Lisa tried to trick her into saying "water", only to get soaked. Lisa explained that the water dumper was French, and "'eau' is the French word for 'water'"... and promptly got soaked herself.
** The 1984 episode "Weather and Seasons" featured a heat wave where Christine and Lisa tried to invoke the water drop, only to learn that all the water had evaporated.
** In 1985's "Revenge", Lisa was caught off guard when saying "water" did not trigger a drenching. Thinking the word no longer worked, she tried "[=H2O=]", "[[GratuitousGerman Wasser]]", and "[[GratuitousSpanish Agua]]"... which finally brought down a bucket of water. Alasdair noted that she had not met Julio, the new stagehand.
** The 1986 episode "Enemies and Paranoia" referred to a Soviet version of the show where one gets covered in ''red'' slime whenever one said "free".
* SelfDeprecation: Many of the jokes were about how awful/boring the show was.
* ShotAtDawn: A regular sketch involved one of the kids about to be shot by a firing squad, led by El Capitano. The sketches generally ended one of three ways: either the kid would trick El Capitano into freeing him/her (leading him to mutter, "That is one sneaky kid!"), or the kid would trick El Capitano into being shot by his own men (usually by standing in front of the post and saying "fire" in an unrelated context), or the kid would fail to trick El Capitano and would be left wincing as he shouted "Ready!... Aim!..." before a cut to the next sketch.
* ShoutOut: Several to ''Series/MontyPythonsFlyingCircus''. To begin with, the opening titles are reminiscent of Terry Gilliam's animations.
** In the ''Whatever Turns You On'' episode "Educational Programming", Ross is asked why programming that is both educational and Canadian cannot include such topics as lumberjacks. Ross mentions that he used to be a lumberjack, and sings "And I'm OK..."
** The same episode features a reluctant Kevin Somers as the Don't Bee, whose entrances are always accompanied by the battle cry, "Nobody expects the Don't Bee!"
** The 1981 episode "Safety First" features a cinema sketch in which an elderly patron (Christine [=McGlade=] in heavy makeup) brings her pet python to a travel film about South America. The python's name? Monty.
** Several early episodes featured characters getting 16-ton weights dropped on them.
** The 1985 episode "Identity Crisis" includes a camp sketch in which Justin Cammy is looking glumly at a poster of Norway and tells a puzzled Alasdair that he is "pining for the fjords".
** Running the end credits in the middle of the "Priorities" episode may be considered a nod to Monty Python, who ran the closing credits after the first sketch in one episode (and right after the ''opening titles'' in another).
* SlidingScaleOfIdealismVersusCynicism: The series was much closer to the cynical end, particularly in its portrayal of adults as [[AdultsAreUseless bumbling idiots, scheming con artists, or cackling sadists]]. As mentioned in AdultsAreUseless, series co-creator Roger Price took this angle deliberately as a rebuttal to the more idealised portrayal of adults in most children's series as helpful, morally upstanding, {{Reasonable Authority Figure}}s.
* SpiritualSuccessor: ''Series/AllThat'', or for Canadian viewers, YTV's mid-1990s sketch/variety series ''It's Alive!''
** The show itself is a complicated case of one. What remains of the 1979 season is almost entirely unrecognizable as ''You Can't'', lacking most of its defining characteristics as well as its layout. ''Whatever Turns You On'', which aired for one season between 1979 and 1981, gave ''You Can't'' most of its cast, layout and running gags as well as its style of humor. But it technically came second. Make of that what you will.
* TheStinger: In every episode, there was at least one scene after the credits which sometimes tied up a recurring plot for the episode. Just to give a few examples:
** "Christmas" from 1984 wraps up the plot of Alasdair trying to get a kiss out of the girls in the cast with mistletoe by having Lisa, Vanessa, and Christine kiss him in turn and say, "Merry Christmas." However, Vanessa warns him, "Christmas only comes once a year, and tomorrow is another day!"
** The 1984 episode "Science" ends with a stinger in which Ross reveals that Alasdair's recital of the recipe for green slime, which he has spent the entire episode researching, has been obscured by the credits music. He proceeds to confiscate and eat the paper on which Alasdair has written the recipe.
** "Enemies and Paranoia" from 1986 ties up the "B-plot" of Adam Reid's wrestling bout with the Masked Destroyer by having Adam unmask the Destroyer to reveal... Mrs. Prevert, who drags him home by his ear. As she forces him to sit down to a huge plate of Brussels sprouts and recites further punishments, Adam groans, "With a mom like this, who needs enemies?"
* SuspiciouslySimilarSubstitute: The entire cast over time, and especially when they replaced ''everyone'' for the 1989 and 1990 seasons.
* TakeThat: The series took plenty of potshots at other television series, particularly children's series which fell closer to idealism on the SlidingScaleOfIdealismVersusCynicism, but its favourite target was... [[SelfDeprecation itself.]]
-->'''Christine:''' ''(holding up an Atari 2600 cartridge)'' Now ''this'' is the ultimate video cartridge. It lets you play with your favourite TV programme and do what you've always wanted to do. Like, you could shoot down all those stupid little [[Franchise/TheSmurfs Smurfs]], or you could make the [[Series/TheDukesOfHazzard Dukes of Hazzard]] get into a twenty-car collision, or... you could sink the [[TheLoveBoat Love Boat]]... think of it! You could commit arson- ''(a yellow "THE END" screen appears accompanied by the final chord from Music/TheBeatles' "A Day in the Life")'' ... okay, which one of you guys out there has one of these cartridges?
* TortureTechnician: The monocle-and-eyepatch-wearing,[[note]] which eye has which varies from one sketch to the next[[/note]] giggling German dungeonkeeper Nasti had a wide array of torture methods for the kids in his dungeon, ranging from racks and thumbscrews to having Lisa Ruddy talk their ears off.
* TransAtlanticEquivalent: The 1979 incarnation of the series was itself the Trans-Atlantic Equivalent of the [[Creator/{{ITV}} Thames Television]] children's series ''You Must Be Joking!'' (1975-76) and ''You Can't Be Serious!'' (1978), which also featured casts of (mostly untrained) child actors with special celebrity guests and musical guests, used CoveredInGunge as a comedy device, and were created by ''YCDTOTV'' co-creator Roger Price. The cast of ''You Must Be Joking!'' included lifelong friends and acting partners Pauline Quirke and Linda Robson (then in their teens), most well-known as the co-stars of the sitcom ''Series/BirdsOfAFeather''.
* VideoArcade: In a nod to the popularity of arcades in the 1980s, one of the regular settings for sketches was "Blip's Arkaid". Blip (Les Lye), the owner, was a money-hungry price-gouger who deliberately sabotaged the machines if the kids were on the verge of winning free games.
* VomitDiscretionShot: Whoever figures out what (or who) is in the burger in Barth's diner always chucks. Sometimes into buckets typically provided by said Barth. How else do you think he gets his "Special Sauce"?
* VoodooDoll: In the "Jealousy" episode from 1984, Christine gets a raise while the other cast members do not. Lisa joins Christine for the introduction and claims not to be jealous, only to dig out a voodoo doll and stab its head with pins until Christine is forced to leave the stage with a headache.
* WhoEvenNeedsABrain: A sketch had a mother getting far too enthusiastic about cleaning out her child's ears, and cleaning out everything between them as well. It had no noticeable effect on the child.
* WhoWritesThisCrap: The kids often complained about the bad writing on the series (the locker jokes were a particularly common target for their vitriol). See LamePunReaction for an example.
