Educational program from the creators of ''Series/SesameStreet'', the Children's Television Workshop, which originally ran on Creator/{{PBS}} from 1987 to 1992. ''Square One Television'' was a half-hour sketch show which featured music videos, game shows, animations and parodies of other popular television programs designed to teach UsefulNotes/{{mathematics}} to children. Ironically, ''Square One Television'' was often criticized for being too entertaining. Some people just couldn't believe that it was really possible for something that children actually enjoyed watching to be educational. It is also notable for the large amounts of ParentalBonus (often coming in the form of [[ShoutOut shout outs]] to the UsefulNotes/UniversityOfMichigan, where many of the creators matriculated). A number of shorts were the earliest projects for [[WesternAnimation/{{Doug}} Jumbo Pictures]].

Its stated goal was "To promote positive attitudes toward and enthusiasm for mathematics by showing that: A. Math is a powerful and widely applicable tool useful to solve problems, to illustrate concepts, and to increase efficiency. B. Math is beautiful and aesthetically pleasing. C. Math can be understood by, be useful to, and even be innovated by nonspecialists." For all the claims of being overly entertaining, it did an excellent job in this, presenting an engaging introduction to a fair number of deep mathematical concepts, including Fibonacci Numbers, Pascal's Triangle, Bases Other Than 10, The Golden Section, Imaginary Numbers and Diophantine Equations.

Recurring animated segments featured Mathman (an affectionate parody of VideoGame/PacMan in a Wolverines helmet, who existed to demonstrate common mathematical errors, and who would be eaten by his nemesis, Mr. Glitch, in a truly freaky FamilyUnfriendlyDeath for getting answers wrong) and Dirk Niblick of the Math Brigade (a WesternAnimation/RogerRamjet-like character [who even shared Ramjet's voice actor, Gary Owens; his animator, Fred Crippen, and his creator-writer, Jim Thurman] on the far shallow end of the BadassNormal scale, who uses his skills in math to help his friends and defeat scam artists). ''Every'' episode ended with part of a five-part "Mathnet" story (featuring a supposed "Mathnet" wing of the Los Angeles, and later New York, Police Department, whose members would use their skills in mathematics to solve crimes). "Mathnet" was particularly filled with Parental Bonuses (largely due to it being a parody of ''Franchise/{{Dragnet}}'') to the extent that collections of each serial were run in prime time on various PBS stations.

!!This + show + provides + examples + of =:

* TwentyPercentMoreAwesome: There's a skit with a man singing about how he was giving "Eight Percent of my Love" to his girlfriend, with a breakdown for where the other 92% was going.
* AbnormalAmmo: Mathnetters Kate Monday, George Frankly, and Pat Tuesday on ''Mathnet'' carry calculators as their primary weapons, instead of handguns (and may wield them in such a way). Averted, however, with [[DaChief Captain Joe Greco]] and Benny Pill in the New York era, as they wielded (but never fired) actual guns to apprehend suspects.
* AdvertisedExtra: Despite Los Angeles Mathnet boss Chief Thad Green making very few in person appearances, his actor, Creator/JamesEarlJones, was always billed in the main cast alongside Beverly Leech (Sgt. Kate Monday), Joe Howard (Det. George Frankly), and Mary Watson (Technical Analyst Debbie Williams). Unlike other instances of this trope, however, this generally only occurred in story arcs that Jones was actually appearing in. Similarly, in the New York era, despite New York Mathnet boss Captain Joe Greco making only slightly more in person appearances than Green did, his actor, Emilio Del Pozo, was always billed in the main cast alongside Beverly Leech, Toni Di Buono (Sgt. Pat Tuesday) when Leech left, Joe Howard, and Bari K. Willerford (Officer Benny Pill). Again, this generally only occurred in story arcs that Del Pozo was appearing in.
* AffectionateParody: The show was almost entirely constructed of affectionate parodies presenting mathematical ideas - from sitcoms (such as ''[[Series/TheHoneymooners The Phoneymooners]]'', ''[[Series/FawltyTowers Nobody's Inn]]'', and ''[[Theatre/TheOddCouple The Odd Pair]]'') to game shows (''[[Series/WhatsMyLine What's My Number?]]'', ''[[Series/WheelOfFortune But Who's Counting?]]'', and ''[[Series/LetsMakeADeal Let's Do a Deal]]'') to science fiction (''[[Series/MaxHeadroom Fax Headfull]]'') to dramas and soap operas (''[[Series/GeneralHospital General Mathpital]]'' and quintessentially ''[[Franchise/{{Dragnet}} Mathnet]]'') to video games (''[[VideoGame/PacMan Mathman]]'' and ''[[VideoGame/QBert Pauline's Perilous Pyramid]]''), as well as most of the musical numbers.
* ArcNumber: In Kate Monday / Pat Tuesday's voiceover narrations for ''Mathnet'', the times mentioned are always 43 minutes past the hour.
* BasedOnAGreatBigLie: ''Mathnet'', in the beginning of each segment.
--> '''Narrator''': The story you are about to see is a fib, but it's short. The names are made up, but the [[UsefulNotes/{{Mathematics}} problems are real.]]
* TheBermudaTriangle: In a ''Mathnet'' segment titled "The Case of the Bermuda Triangle," Pat and George debunk the Bermuda Triangle myth on television, leading to a case where a sunken boat could prove a man's innocence of treason.
* BrokeTheRatingScale: Stanley O'Toole from the song "Less than Zero" manages to get negative scores in activities you wouldn't think it possible to do - diving, dancing, and rollerskating. Then he tries the hammerthrow and throws it backwards, so his official distance is -55 feet.
* TheButlerDidIt: The outcome of one the ''Mathnet'' cases, with the twist that [[spoiler: the butler was actually the owner of the mansion in disguise.]]
* ButtMonkey: Mr. Beasley is often taken in by various math based scams, but luckily he has next door neighbor Dirk Niblick to expose the fraud and save the day. His other next door neighbor is George Frankly, who repeatedly borrowed and lost his things.
* TheCaseOf: The ''Mathnet'' segments were generally named this way, though in the first season they were usually named "The Problem of..." instead.
* ClearMyName: George Frankly in "The Trial of George Frankly" when he's accused of robbing a bank, and Pat Tuesday, when she's accused of stealing jewelry.
* ClearTheirName: Kate Monday's old college friend, Eve Adams, when she's accused of kidnapping.
* CliffHanger: Generally used at the end of every ''Mathnet'' segment except the final one in a set.
* {{Cloudcuckoolander}}: One ''Mathnet'' interrogation subject was a young woman who said that she was walking her dog (except she didn't really have one) and explained that her mother always said she had a great imagination - then she also mentioned something about a 'mean pterodactyl' and how she hoped it wouldn't get her dog.
* ContentWarnings: Parodied at the beginning of re-packaged airings of ''Mathnet'', read by Joe Howard in character as George Frankly. For example, the following aired as an introduction to "The Calpurnian Kugel Caper":
-->The Mathematician General has determined that the following program contains graphic depictions of mathematics, including adult mathematicians generating random numbers, probability, correlation versus causality, and, of course, a talking llama. Viewer discretion is advised. ''(George Frankly signature laugh)''
* ContinuityNod: In one episode of "The Problem of the Maltese Pigeon", Kate Monday and George Frankly are searching Jasper Stoutman's house for the eponymous statuette. George finds a baseball in the fireplace, a nod to the climax of "The Problem of the Missing Baseball".
* ControllableHelplessness: At the end of most ''Mathman'' segments, after getting a wrong answer Mathman attempts to escape from Mr. Glitch, but there seems to be no way for him to actually get away, so his death is inevitable.
* DaChief: In the L.A. era of ''Mathnet'', Chief Thad Green. In the New York era, Captain Joe Greco.
* DayOfTheWeekName: Kate Monday, Pat Tuesday.
** In the skit "The Adding Family", a girl named Thursday is mentioned.
* DisasterDominoes: In the ''Mathnet'' episode "The Case of the Deceptive Data", Kate and George are interviewing data tampering suspect Dwight Ledbetter (Jack Riley), who claimed to have broken his leg on the night of the tampering. After turning down a live sales call by two LAPD officers of tickets to the Policemen's Ball, he closed his front door and accidentally stepped on his cat. Jumping up in shock, he landed on his wife's skateboard and shot into the kitchen, bounced off the fridge door his son had just opened, and skated out of the back door and into his neighbor's driveway, where his neighbour, returning from a garden party, ran over his leg with a riding lawnmower. As Kate and George turn to leave, they hear [[ThatPoorCat a cat screech]], followed by Ledbetter yelling "''[[OhNoNotAgain Not again!]]''" as further sounds of chaos issue forth, ending with the sound of a lawnmower.
* DisneyDeath:
** [[spoiler: George Frankly]], in "The Case of the Great Car Robbery". [[spoiler: They thought he was crushed in the junkyard along with the car they had rented over at LAX as their way of setting up a trap, so that they would be able to follow the lead of the head of the car theft ring, Henry Edsel III. George managed to roll out of the car, the moment he was about to be crushed.]]
** Again, in "The Case of Bermuda Triangle", wherein [[spoiler:George's life is sought by Donnawhy, who was after the treasure the Mathnetters were seeking for Trudy. Luckily, George had surfaced quickly upon finding the loot and was picked up by the cops.]]
* DrosteImage: Used in a sketch to demonstrate the concept of infinity.
* EarlyInstallmentWeirdness: The original pilot for ''Mathnet'', the shows' most popular segment, was titled "The Problem of the Missing Baseball". It had a different opening title sequence, Ginnie Carlson as the Mathnet duo's technical analyst instead of regular technical analyst Debbie Williams, and, among other differences, was exactly like ''Dragnet'', from the setting, to the rapid-changing close-ups during a conversation. It was filmed in one week in August 1985. [[note]]Each episode ended with a bumper that said "Mathnet Founded 1985: To Cogitate and to Solve." 1985 represented the year the pilot episode was filmed.[[/note]] It was also the shortest ''Mathnet'' episode ever, at just under 33 minutes in length. The longest one was "Despair in Monterey Bay", at just under 87 minutes in length.
** Likewise, the original ''Mathman'' pilot had Mathman eat numbers that were smaller than 1/2. In that episode, the narrator says "When a number crosses your path...", instead of the usual "When you encounter a number...". An extremely earlier version of that episode (Mathman approaching a 1/3) can also be seen briefly in the opening credits to seasons 1-3, with a very funny-looking early version of Mathman and Mr. Glitch.
* EducationalSong: Every episode featured at least one musical number, with the songs explaining everything from perpendicular lines to percentages to Roman numerals to map scales.
* EpisodeCodeNumber: Like most, if not all of CTW's productions, this show displayed its production code at the start of each episode. Each episode had a three-digit code; the first digit represented the season number, and the next two digits represented the episode number.
** '''Season 1 -''' 101-175
** '''Season 2 -''' 201-240
** '''Season 3 -''' 301-340
** '''Season 4 -''' 401-440
** '''Season 5 -''' 501-535
* EveryEpisodeEnding: Each episode of ''Mathnet'' usually ended with George Frankly and Kate Monday (later Pat Tuesday) giving each other a high-five, followed by a picture of the recently-arrested criminal, and a narrator explaining what became of said criminal.
** Doubly subverted in "The Parking Meter Massacre", where one criminal is arrested, and the Mathnetters think the case is solved, and make George's signature laugh at each other instead of the high-five. But they thought wrong....
* EvilGloating: Inverted in a ''Mathman'' sequence where Mathman disputes the idea that math is only used in school. Unfortunately, he monologues so long that he neglects the seven-second timer, and gets eaten.
* FailureIsTheOnlyOption: In ''Mathman'', Mathman will ''usually'' get eaten by Mr. Glitch as he will eventually get an incorrect answer. Ditto for Mr. Glitch getting eaten whenever he runs in place of Mathman.
* FakeGuestStar: In the L.A. era of ''Mathnet'', Officers Sam and Steve, played by Sam Salazar and Steve Fellman. Despite appearing in every Los Angeles story[[note]]usually at the end, where they would be shown taking whoever happened to be the VillainOfTheWeek into custody, but they would sometimes appear earlier in the story as well[[/note]] they were always listed in the guest cast. Also overlaps with CastTheExpert, as both men were actual police officers working for the LAPD at the time.
* FallenOnHardTimesJob: In one ''Mathnet'', George and Kate come across a youngster selling pencils in the park. At first George decides to take pity on him but when he finds out that the pencils are being sold for $50,000 each, he has second thoughts.
-->'''George:''' Isn't that a little much for a pencil?\\
'''Boy:''' Yeah, but I only have to sell ''one''...
* GettingCrapPastTheRadar:
** In the music video for "Graph of Love", the intro concerns a group of teenage girls noticing that a friend's relationship must've gotten serious, as there is a "diagram" in her purse.
** Part 5 of the ''Mathnet'' episode "The Trial of George Frankly", when the real George arrives at the courtroom, with just his undershirt and heart boxers, to expose the fake one.
--->"May it please the court! ''I'' am George Ernest Frankly, and I just came out of the closet!"
* GoofyPrintUnderwear: In "The Trial of George Frankly", George shows up wearing heart-patterned boxer shorts.
* GoshDarnItToHeck: Whenever someone is sworn in during "The Trial of George Frankly":
-->'''Bailiff''': Do you swear to tell the truth, the whole truth, and nothing but the truth, so help you Gosh?
* IncrediblyLamePun: In one ''Mathman'' skit, Mr. Glitch explained that Mathman wasn't ready to play because [[PottyEmergency "he's in the mathroom"]].
* InternalAffairs: Averted in the ''Mathnet'' segments. In the respective ClearMyName story arcs, the Mathnetters meet directly with DaChief.
* JurisdictionFriction: Averted in the ''Mathnet'' segments. Whenever the Mathnetters happen to meet up with an outside organization, said organization is very willing, and often excited, to be working together with ''Mathnet''
* KaizoTrap: In one ''Mathman'' skit, our hero successfully completed the maze and won a free game. When that bonus game started a few minutes later, a screen-sized Mr. Glitch ate Mathman ''[[TheComputerIsACheatingBastard during the introduction]]'' (that same bonus game was shown by itself in later episodes).
-->'''Announcer:''' ...and beware the humorless Mr. Glitch... he will... ''[{{Beat}}]'' ...eat you.
* KlutzTheSurgeon: Doctor Mal Practice from ''General Mathpital''.
* KnightsAndKnaves: A "Spade Parade" sketch features the three-person variant with the Wisenheimer brothers, Tom (knight), Dick (knave), and Harry (alternator). Fortunately for Spade, when he tries to establish their identities, Harry gives himself away by claiming to be Dick (neither the knight nor the knave would claim to be the knave), and Dick gives ''him''self away by claiming to be Harry; had they all claimed to be Tom, Spade would have nothing to go on.
* LaserGuidedKarma: Mr. Glitch cheated a couple of times, eating Mathman too soon. When Mr. Glitch himself ran the maze, he screwed up quickly, once getting eaten by Mathman's dog.
* LatexPerfection: The fake George Frankly in one episode of ''Mathnet'' was revealed to be wearing a latex mask. Subverted immediately afterwards when George attempts to pull the mask off the fake George's accomplice:
-->'''Accomplice''': Ow! The nose is real, try the hair!
* LogicBomb: In a sketch parodying ''Film/TwoThousandOneASpaceOdyssey'', a pair of astronauts stop their computer from singing "Row, Row, Row Your Boat" all day long by giving it an unsolvable algorithm: Start with 3, add 2, if answer is even, stop, if odd, add 2 again, repeat. Why exactly listening to the computer count by twos to infinity was less annoying than listening to it sing remains a mystery.
* LogoJoke: At the end of the series premiere episode, the PBS logo clones more PBS logos as we hear the chorus sing "And on, and on, and on, and on..." in a nod to the episode's opening musical number, "That's Infinity".
* MeaningfulName: If you can puzzle out what Mrs. I.O. Privacy's first and middle names were, [[spoiler:you'd know that she dood it]].
* MediumAwareness:
** The "Dirk Niblick" segments have NoFourthWall, and so the characters frequently mention their status as cartoon characters. For example, when the Noodleman siblings, Fluff and Fold, drop by Dirk's house, the following exchange takes place:
--->'''Dirk:''' Well, if it isn't the Noodlemans, come to pay a call!\\
'''Fold:''' If it isn't the Noodlemans, come to pay a call, we're in the wrong cartoon!
** The characters in ''Mathnet'' are clearly aware of their status as characters in a television series.
*** The PreviouslyOn introductions by Kate (or Pat) frequently mention "look[ing] at scenes from previous episodes".
*** In the Thursday episode of "The Problem of the Dirty Money", George observes, "In Tuesday's show, Mrs. Swaggle mentioned that the house had a carport."[[note]] Although the scene actually happened in the Wednesday show.[[/note]]
*** In "The View From The Rear Terrace", Kate Monday is stuck at home with a broken leg. The start of Tuesday's episode has George comment that this is where they'd look at the previous episodes, but Kate was the one that knew how to do that, so George looks at his notebook instead and goes over the previous episode without footage. The last note reads "Pick up bell peppers for meatloaf" and George says that he'll do that in Thursday's episode.[[note]] And he does.[[/note]] Oddly, the rest of the episodes have previous footage in them.
* MoebiusNeighborhood: Averted; George Frankly and Dirk Niblick both have only one neighbor--but it's the same neighbor, Mr. Beasley.
* MoodWhiplash: When Pat and George are investigating disappearances from a staged Creator/AgathaChristie-like mystery weekend, they check the victims' rooms. George keeps complaining that everyone else has a bigger closet than he. [[spoiler:That's actually a clue.]]
* NamedAfterSomebodyFamous: The criminal in one of the ''Mathnet'' storylines is named [[Creator/CaryGrant Archie Leach]].
* NoCelebritiesWereHarmed: Used often in the ''Mathnet'' segments.
** In "The Problem of the Missing Monkey", George makes a reference to the fictional movie star, [[Creator/SylvesterStallone Sly Balboa]].
** "The Problem of the Passing Parade" involves the rescue of rock star [[Music/BruceSpringsteen "Steve Stringbean"]], who had been taken hostage by people who wanted to replace rock and roll with [[{{March}} marches]].
* NoPronunciationGuide: In "The Trial of George Frankly" episode of ''Mathnet'', there's a running gag about the pronunciation of the last name of the two criminals (two brothers) that might be trying to have George framed for a bank robbery.
-->"I remember them. The brothers Karamazov (KAIR-ah-mah-zoff). Or was it kair-ah-MAHZ-off?"
** The judge takes it a step further by pronouncing it ka-RAAH-ma-zoff.
* ParodyCommercial: "'Oops' is brought to you by erasers! Don't make a mistake without one!"
* PreviouslyOn: The Tuesday through Friday episodes of ''Mathnet'' began with summaries of previous episodes (Kate/Pat even mentioned "[[MediumAwareness look[ing] at scenes from previous episodes]]").
* ReadingTheStageDirectionsOutLoud: Happens often in the [[NoFourthWall fourth wall-lacking]] "Dirk Niblick" segments. For example, in an episode about rounding, the Noodleman siblings, Fluff and Fold, are shocked to discover that their haphazard use of rounding has led them to underestimate the price of their purchases:
-->'''Fluff, Fold:''' ''Three dollars and four cents, [[WantonCrueltyToTheCommonComma question mark, exclamation point, question mark, exclamation point?!?!]]''\\
'''Cashier:''' That's right, three dollars and four cents, period.
* RearWindowWitness: ''Mathnet'' used this plot: Kate is housebound with a broken leg and suspects that her neighbor is a mad bomber. Luckily, George believes her (and is significantly more mobile).
* TheReasonYouSuckSpeech: Comical version. In the "Spade Parade" sketch with the KnightsAndKnaves puzzle (see the corresponding entry), Tom (the knight) delivers one to Spade as he is ushered out by his employer, Vanessa Van Vandervan.
-->'''Tom:''' I ''hate'' your hat. And your office is ''abysmal''. And-\\
'''Vanessa:''' Tom... ''(begins pushing him out of the door)''\\
'''Tom:''' -that tie belongs in a 1942 [=DeSoto=]! And your eyes are too close together, and you're too thin for your own-\\
''(Vanessa finally closes the door behind her, but Tom immediately re-opens it)''\\
'''Tom:''' -good! ''(he slams the door; Spade looks momentarily self-conscious about his weight, then shrugs it off)''
* ReferenceOverdosed: The series is packed with references to films, television series, and popular culture, most of which would have been over the heads of the target audience; the ''Mathnet'' serials in particular are a goldmine of ParentalBonus.
* RoadSignReversal: This is an important plot point in an episode of ''Mathnet''. George Frankly had two invitations to a mystery weekend at The Qualms, a quaint inn in the woods, where he would essentially be roleplaying as SherlockHolmes. While making their way there, he and partner Pat Tuesday fail to notice that the wind blew the sign in a different direction until later. [[spoiler:The butler informs them that they're not at the inn they thought they were, meaning that the kidnappings they thought were part of the roleplay are in fact real.]]
* ScoobyDoobyDoors: "Ghost of a Chance".
* SesameStreetCred: This show was made by the same company that does ''Series/SesameStreet''. Music/WeirdAlYankovic'' appeared several times as himself and there were at least a few other big names that appeared as themselves as well.
* SheWhoMustNotBeSeen: George Frankly's wife Martha, whose favorite recipe is apparently meatloaf. Together, they have no children, as indicated in one episode where [[spoiler:the fake George, portrayed by Irving Karamazov, blew his cover by admitting he's guilty, and apologizing to the following people he may have hurt: "My friends, my sixth grade teacher Mrs. Burk, my scout master Mr. Hare, and of course, my beloved wife Martha, and our ''FINE CHILDREN''".]]
* ShockinglyExpensiveBill:
** In the ''Mathnet'' episode "The Problem of the Dirty Money", George was working undercover as a diner cook, and had to deal with a patron who didn't expect tax on his bill, snarling, "I didn't order tax on my hamburger, just ketchup!" Of course this was just an excuse to deliver some Educational Programming about tax and percentages. The bill wasn't that much bigger than he expected ($3.20, California sales tax at the time being 6.5%, vs. $3.00), but it was bigger.
** In a "Dirk Niblick" segment, siblings Fluff and Fold have three dollars to spend on birthday presents for a set of quadruplets, and they estimate that their four toys cost the full three dollars. However, because Fluff has rounded her prices up and Fold has rounded his prices down, they are four cents short, leading to the outburst in ReadingTheStageDirectionsOutLoud.[[note]] In an interesting contrast to the ''Mathnet'' example, the listed prices of the toys already include tax.[[/note]]
** Another "Dirk Niblick" segment had everyone in town lamenting their shockingly expensive bills, like Mr. Beasley lamenting that he didn't know the car he just bought cost $400,000! (It turns out that no one in town noticed the decimal point, "a little dot that makes a big difference", and his car only cost $4,000'''.00'''.)
* ShoutOut:
** Many to the University of Michigan; executive producer David D. Connell and senior producer and head writer Jim Thurman were both [=UMich=] graduates.
*** Mathman wears a Michigan helmet.
*** When Dirk Niblick takes phone calls from his mother, the inflections of her voice sometimes form the melody of the Michigan football team fight song, "Hail to the Victors".
*** Various segments illustrate how many of a particular item (such as ping-pong balls) it would take to fill Michigan Stadium.
*** In the earlier seasons, Mathnet chief Thad Green (James Earl Jones, also a [=UMich=] alum) has a Michigan pennant on his office wall.
*** One "Oops!" mistake was implied to have led to the 1923 filmed collapse of the seven-winged [[http://en.wikipedia.org/wiki/Gerhardt_Cycleplane Gerhardt Cycleplane]]. The designer of the aircraft, W. Frederick Gerhardt, was the head of the Department of Aeronautical Engineering at Michigan in the 1920s.
** In the ''Mathnet'' episode "The Case of the Dirty Money", when Kate asks George what he did last night, George replies that he was watching a rerun of Jack Webb in ''Franchise/{{Dragnet}}'', describing it as a "great series."
** This memorable line from the ''Mathnet'' episode "The Trial of George Frankly":
--->[[Series/GetSmart "It's an easy trick for the prosecuting attorney to create a bunch of witnesses through here, accusing the defendant of being a robber, a liar, and a fraud, it's easy for him. He's got proof. But what about me?"]]
** In "The Case of the Deceptive Data", the character of Vicious Vinnie Vermin wears clown makeup patterned after Emmett Kelly's "Weary Willie" character. [[spoiler:At the end of the serial, the crimes of which he is convicted include "an 812: using Emmett Kelly's makeup to misinform kids".]]
** The contestants played by the regular cast members in "But Who's Counting?" sometimes had names that referenced real people. For example, one episode featured the Maldens, Karl and Priscilla (who both had large noses similar to that of the real Karl Malden and made various references to his then-contemporary status as the frontman of American Express' "Don't leave home without it!" ad campaign), against the Sullivans, Gilbert and Edna (named for British songwriting duo Creator/GilbertAndSullivan and American variety host Ed Sullivan; they were stated to be from [[Theatre/ThePiratesOfPenzance Penzance, England]] and delivered all of their lines in precise rhythm while conducting themselves with batons).
* ShownTheirWork: The penal code numbers for crimes given at the end of Mathnet episodes are more or less correct.
* ShowWithinAShow: Many of the game shows depicted were essentially clones of other popular game shows, given a mathematical twist, such as ''Series/FamilyFeud'' ("Piece of the Pie"), ''Series/TheHollywoodSquares'' ("Square One Squares"), ''Series/ThePriceIsRight'' ("Close Call"), ''VideoGame/PacMan'' ("Mathman") and others. While some of the parodied game shows remained mock parodies, many of them were actual mini-game shows in their own right, using actual child contestants and even awarding small prizes with the show's branding. In addition, they would also always be hosted and announced by the regular ''Square One TV'' cast members using their real names, as opposed to using fake names that they would use in sketches in which they were playing fictional characters.
* SignatureLaugh: George Frankly of ''Mathnet''.
* SimilarItemConfusion: One brief sketch showed two men who were working at a restaurant discussing income and profit. One of the bills they were discussing involved window repair due to a customer's demonstration of how hard the Swedish Meatballs were, to which the cook replied "How was I supposed to know that flour and plaster weren't the same thing? I mean they're both all powdery and white...!"
* SpiritualSuccessor: ''{{Series/Numb3rs}}'', much like ''Mathnet'', has detectives using mathematics to solve crimes.
* SpottingTheThread: In "The Trial of George Frankly", George confesses to the bank robbery, and says how sorry he is to his wife and children. The real George Frankly has no kids.
* StealTheSurroundings: In the first story arc of ''Mathnet'', "The Problem of the Missing Baseball", a woman's house is stolen in order to find some gold bricks which had been hidden in the house. [[spoiler: The house was stolen by XY-313, one of the few helicopters that could steal one. The chopper was piloted by a man named Clarance Sampson ([[IHaveManyNames alias Charles Sampson, alias Carl Sampson, alias William Howard Taft Sampson)]], because the house belonged to an accomplice of his, and he needed the gold that was in there.]]
* StockFootage: The "Oops!" mistakes are implied to lead to various stock footage misfortunes, such as the 1940 collapse of [[http://en.wikipedia.org/wiki/Tacoma_Narrows_Bridge_%281940%29 Gallopin' Gertie (the Tacoma Narrows Bridge)]], or the 1923 collapse of the [[http://en.wikipedia.org/wiki/Gerhardt_Cycleplane Gerhardt Cycleplane]].
* SuspiciouslySimilarSubstitute:
** When Kate Monday left, Pat Tuesday replaced her. She had the same deadpan delivery style as Kate, as well as a good deal more common sense than George Frankly. Likewise, when Kate and George moved to New York, Captain Joe Greco replaced Chief Thad Green as DaChief. Averted, however, with Benny Pill replacing Debbie Williams in the move to New York, as their respective jobs within the Mathnet organization were drastically different. While Debbie was a technical analyst and thus she mostly stayed at the station, Benny was a taxi driver/undercover cop and thus he would often accompany Kate/Pat and George out in the field.
* SwappedRoles: When Mathman is unable to play his mission (for example: Mathman is busy walking his dog), Mr. Glitch would substitute Mathman's mission. In one episode where he needed to make an answer that was less than seven, he ended up being eaten by Mathman when he picked a zero. In the other episode, He answered true but it was a false answer and was eaten by Mathdog.
* TakeThat: Just as the series featured many {{Shout Out}}s to the University of Michigan, so it took potshots at the university's athletic rivals, such as Michigan State University (multiple ''Mathnet'' episodes featured villains who had graduated from MSU, in some cases after flunking out of Michigan) and Ohio State University (in another ''Mathnet'' episode, a theft of $136 from the OSU alumni fund is said to have "cleaned the whole thing out").
* TalkingIsAFreeAction: Averted when Mathman discusses using math when one would get a job. He talks too long explaining his reasoning for answering true and false questions which allows The Glitch to devour him.
** He does it ''again'' on a later true-or-false question. [[TooDumbToLive Even after Mr. Glitch warns him multiple times]]. Getting preachy about math may very well be Mathman's hubris.
* TemptingFate[=/=]PrideBeforeAFall: Does Mathman say "I'm smart!" before he's done? Then you can expect him to screw up within the next couple decisions.
* TheBadGuyWins: The result of most ''Mathman'' segments (though [[InvertedTrope inverted]] on the rare occasions that Glitch played).
* ThisIsAWorkOfFiction: At the beginning of every ''Mathnet'':
-->The story you are about to see is a fib, but it's short. The names are made up, but the [[MultipleReferencePun problems]] are real.
* {{Tomboy}}: Kate Monday was one - George awkwardly suggests she wouldn't have been interested in toy trains because she was a girl, and she points out that she had a train set, a baseball glove, and a hockey stick.
* TotallyRadical: In a dual parody of ''Series/AmericanBandstand'' and ''Series/{{Star Trek|TheOriginalSeries}}'', Captain Jamie Lee Curt and Science Officer Sprock of the Starship ''Interface'' accidentally beam into a recording of ''American Blandstand'' with [[Creator/DickClark Rick Clark]]. After the two take a moment to get their bearings, Curt decides that he and Sprock should "try and speak his language", and proceeds to clumsily pepper his speech with 1950s slang (Sprock, of course, sticks with SpockSpeak). Clark is also trying too hard to fit with the times, but for [[WereStillRelevantDammit the opposite reason.]]
-->'''Curt:''' ''(stiltedly)'' Say, hep cat... quite a, uh, groovy pad you got here, uh, you dig?\\
'''Clark:''' ''(enthusiastically)'' Hey, for sure, I ''dig!'' Now, maybe you guys would like to join us for a game of "[[PunctuatedForEmphasis Rate - That - Record]]"!\\
'''Sprock:''' Captain, it would be interesting to see some of the society's primitive rituals. I say we proceed.\\
'''Curt:''' Very well. ''(to Clark)'' Uh, right on, daddy-o.\\
'''Clark:''' ''(brightly)'' Daddy-''O!'' Fantastic!
* WhatKindOfLamePowerIsHeartAnyway: [[LampshadeHanging Lampshaded]] in the Common Multiple Man sketch; Common Multiple Man's only superpower is an ability to instantly find common multiples of any set of numbers, which he himself sheepishly describes as "a pretty nutty superpower... well, you go with what you've got."
* WholePlotReference: ''Mathnet'' had several:
** "The Problem of the Maltese Pigeon": Lifted heavily from ''Film/TheMalteseFalcon'' (George even lapses into a Creator/HumphreyBogart impression for the climactic confrontation with Maureen O'Reilly).
** "The View from the Rear Terrace": A spoof of ''Film/RearWindow''.
** "The Case of the Mystery Weekend": A reworking of ''Literature/AndThenThereWereNone'' (the villain even has the same motive).
** "Despair in Monterey Bay": Owes something to ''Film/ToCatchAThief'' (George references the film's title directly, and the villain is named [[Creator/CaryGrant Archie Leach]]).
* YouAreAlreadyDead: ''(Mathman makes a mistake)'' ''(BWOOOOMP)'' However he dodges, Mathman can only delay the inevitable.
