Satan: Appears in "Sunday Go To Meetin' Time," "Clean Pastures," "The Hole Idea," the Bugs Bunny short "Devil's Feud Cake", (a semi-remake of the Sylvester Cat short "Satan's Waitin'" only with Yosemite Sam) and "Now Hear This."
The constant editing for content of these cartoons on all major broadcast and cable networks, and Cartoon Network getting rid of the Looney Tunes cartoons between 2004 and 2009. As of March 2011, the classic shorts are back, but have been on and off the schedule since then. However, they've consistently been shown on Boomerang again since 2013. Unfortunately, they have mostly been airing the same 300 or so (out of 1,000) shorts over and over again since 2011.
Screwy Squirrel: Early Daffy was practically the Ur-Example. Also the pre-Wild Hare proto-Bugs, to the extent many animation historians consider him a different character.
Zigzagged in Tex Avery's "Cross-Country Detours," which shows a realistically drawn and animated frog. The narrator entreats us to an actual scene of a frog croaking, after which the frog pulls out a gun and blows its brains out, followed by a disclaimer card that states that the management of the theater is in no way responsible for the lame puns in this cartoon short.
Seldom-Seen Species: Some people are astonished to learn that the Road Runner and Tasmanian Devil are based on actual animals and weren't simply invented for the cartoons.
Shout-Out / Reference Overdosed: The Looney Tunes are absolutely loaded with references to celebrities and pop culture of their time period, and to comprehensively list them all would practically require an entire wiki in itself, much less a page.
Sliding Scale of Plot Versus Characters: All of the cartoons land firmly on the "Less Plot Than Characters" end of it. The shorts uniformly rely on wafer thin stories and setups, with the characters personalities often taking the center stage.
The 1942 Any Bonds Today? is only 1 minute and 38 seconds long and is in essence a propaganda short where Bugs, Porky and Elmer Fudd sing and dance to motivate people to buy war bonds to support the war effort. It's one of the shortest cartoons available in the Looney Tunes filmography and features no plot or conflict at all.
1968's "Norman Normal", which is entirely dialog-based humor, with none of the slapstick and wacky gags associated with the series. It also didn't feature Mel Blanc or any of the other regular voice artists. In fact, it wasn't called a Merrie Melody OR a Looney Tune; it was instead called a "Cartoon Special".
Old Glory, which has no jokes and is instead a visual retelling of the founding of America.
"Swooner Crooner" has chickens laying mountains of eggs after the roosters sing to them. The short ends with Porky asking the roosters how they did it - to which the roosters demonstrate, resulting in PORKY laying eggs!
"Cock-a-Doodle-Duel" reuses this gag, except the chickens only lay one or two eggs after Foghorn and the rival rooster turn them on. At one point, Foghorn sees the other rooster dancing and promptly lays an egg himself, much to his embarrassment.
Sophisticated as Hell: In one Foghorn Leghorn cartoon, after the rooster pulls a prank on the resident farm dog, the dog reacts this way:
"There's but one cause for me to follow... I'LL MOIDER DA BUM!"
Sound-Only Death: Subverted at the end of Ballot Box Bunny. When Bugs Bunny and Yosemite Sam learn that they lost the election to a literal dark horse, they decide to settle for a Russian Roulette. Sam is the first to hold the gun to his head and pull the trigger, but doesn't get the bullet. When Bugs is the next to do so, the scene irises out to black and we clearly hear a gunshot. However, the scene irises back in on Bugs' side, showing he just missed his head. A second iris-in on Sam's side shows he took the blast instead.
Sound Track Dissonance: Carl Stalling's successor as musical director Milt Franklyn died halfway through scoring the Sylvester and Tweety cartoon The Jet Cage, from 1962. William "Bill" Lava took over and the difference in music is quite jarring.
The same could be said for "Freudy Cat", where Lava's music in the wraparounds clashes with the original Carl Stalling music heard in most of the old clips. Given that "Freudy Cat" centered on Sylvester going to a psychiatrist about his "giant mouse" problem, the schizophrenic (pardon the pun) music to fit the mood could have been done intentionally.
"Devil's Feud Cake" and "To Beep or Not to Beep" are this for any viewer familiar with the original cartoons that make them up: Bill Lava re-scored the old footage so one can compare and contrast what he came up with versus Carl Stalling and Milt Franklyn.
Six cartoons from 1958 had pre-scored background music tracks (called "needle-drop" in the industry) selected by John Seely, employed during a musician's strike. Most of the tracks heard were also used in Gumby and, soon after, Hanna-Barbera's early TV shows and on The Ren & Stimpy Show. Those cartoons were Prehysterical Hare (Bugs Bunny), Bird In A Bonnett (Sylvester and Tweety), Weasel While You Work (Foghorn Leghorn), Hook, Line And Stinker (Road Runner), Hip Hip Hurry! (also Road Runner) and Gopher Broke (Goofy Gophers).
Played for laughs in "Porky's Preview." Carl Stalling parodies the Looney Tunes theme and creates some hilarious off-key scores, especially with "La Cucaracha."
Daffy's voice in Porky's Duck Hunt was originally based on that of producer Leon Schlesinger. Chuck Jones told that after the cartoon was completed Leon had to screen it, so everyone wrote their resignation in advance. Leon never caught on; he thought it was a funny voice.
Chuck Jones's early short "Tom Thumb In Trouble" is played completely straight, and is actually a very good little fairy tale cartoon, just not a funny one. Years later, after he'd matured in his craft, Jones did "I Was A Teenaged Thumb," which uses wonderfully surreal humor and highly stylized, graphic design-style character designs.
Spit Take: In "My Generation G-G-Gap", Porky does a really long one when he sees his daughter on TV at the rock concert.
Split Personality: Daffy pretends to have one in "The Prize Pest", in order to repeatedly scare Porky in his "alter ego" state.
The Sponsor: In the "Birds Anonymous" short, Sylvester joins the titular group to kick the bird-eating habit, and his sponsor is there to make sure he doesn't try to eat Tweety in a moment of weakness. However, the sponsor himself falls Off the Wagon and goes after Tweety, while Sylvester tries to stop him.
Tweety: Once a bad ol' putty tat, always a bad ol' putty tat!
Stalling the Sip: In one short, Yosemite Sam poisons Bugs Bunny's drink. Bugs spins the table so that they switch drinks, Sam switches them back and so on. Bugs refuses to drink until Sam drinks his first, so he does. With his trembling hand, Bugs reaches for his glass and downs the drink, then thanks Sam for the delicious drink. It is then that Sam realizes that his was the poisoned drink.
Stealing from the Hotel: One travelogue short showed a man who collected hotel silverware and towels. He is shown having several of them in his hands and when the camera pulled back, it's revealed he's in a jail cell.
The first opening to The Bugs Bunny and Tweety Show (i.e. the one without the new Darrell Van Citters animation) reuses the Bugs and Daffy song and dance animation from The Bugs Bunny Show's opening.
Stopped Reading Too Soon: A gag in "Hare-Less Wolf" involves Charles Wolf reading instructions on how to operate a hand grenade. He pulls the pin before reading that you only have a few seconds to throw the grenade before it explodes.
Stylistic Suck: "Porkys Funny Pictures", a self-parodying cartoon-within-a-cartoon written and drawn by Porky Pig himself in the short 'Porky's Preview'.
Used as a narrative point in 'Invasion of the Bunny Snatchers': several characters are kidnapped by alien carrots and replaced with inferior clones, all the clones being drawn horribly lazily and animated in ways parodying the most infamously cheap animation methods used in later Hanna-Barbera cartoons.
Submarine Pirates: The plot of Porky the Gob involves a hunt for a pirate sub, staffed by some outlandish characters, one of which has an outlandish uniform and an even more outlandish mustachio. Porky, left alone to guard his ship, manages to fend off an attack by the sub, capture it, and claim the reward.
Sudden Anatomy: During the "Rabbit of Seville" short, Bugs grows an extra finger on each hand when he plays Elmer Fudd's head like a piano, since the music couldn't be played using the four-fingers-per-hand he usually has.
The stripping lizard from "Cross Country Detours" (even though her "anatomy" was blocked with a Censor Box)
Suddenly Voiced: In the cartoons where Wile E. Coyote goes after Bugs Bunny, Wile E. speaks in a pretentious, intellectual voice (though there is one exception: "Hare-Breadth Hurry," where Bugs is recast as the Roadrunner. In that cartoon, as in the usual Road Runner cartoon, Wile E. Coyote didn't speak at all).
His first lines of dialogue, to Bugs in "Operation: Rabbit":
Wile E.: Allow me to introduce myself. My name is Coyote. Wile E. Coyote, genius. I am not selling anything nor am I working my way through college. (Bugs tries to speak) So, let's get down to cases. You are a rabbit, and I am going to eat you for supper. (Bugs feigns fear) Now, don't try to get away. I am more muscular, more cunning, faster and larger than you, and I'm a genius. (Bugs now looking bored) While you could hardly pass the entrance examinations to kindergarten. (Bugs yawns) So I'll give you the customary two minutes to say your prayers. Bugs: I'm sorry, mack, the lady of the house ain't home. And besides, we mailed you people a check last week.
Wile E. does speak in The Adventures Of The Road Runner, a 25-minute feature intended as the pilot for TV series (which would come about in 1966), in which he answers a child's question on why he wants to catch the Road Runner, and then using film to examine his shortcomings. This feature had parts edited for TV into two separate shorts, "Zip Zip Hooray" and "Road Runner-A-Go-Go," other segments were repurposed for the 1963 short "To Beep Or Not To Beep."
The cat from "A Fractured Leghorn" is a mute until the very end of the short, when he tells Foghorn to "shaddap".
In "Hobo Bobo", the one shot character Bobo the elephant says his first and only line ending the cartoon:
Bobo: Batboy, smatboy! I'm still carrying logs!
In "Joe Glow the Firefly", the firefly shouts "GOOD NIGHT!" after being silent beforehand.
Superstitious Sailors: In the short "Hare We Go", Bugs Bunny accompanies Christopher Columbus on his first voyage, which angers his crew because they consider rabbits on board to be bad luck.
Surprise Jump: There's a series of shorts in which a puppy runs behind a cat and barks loudly, causing the cat to jump up in shock and hold on to the ceiling. When there isn't a ceiling, the cat ends up on a tree, a telephone pole, or even the wing of a passing airplane.
Swallowed Whole: At one point near the beginning of "Museum Scream", Sylvester is attacked and eaten by a snake. He manages to climb back out in the next scene, though.
Porky in some of his bouts against Daffy (he is a policeman in "Daffy Doodles" and "Riff Raffy Daffy" for example).
Synchro-Vox: Used in a brief scene in "Invasion of the Bunny Snatchers".
Talking Animal: Subverted in "Unnatural History": A man shows a skeptical producer his talking dog, who answers all his questions with bark variants ("Ruth", "Roof", "Ralph"). The unimpressed producer throws them out, and the dog asks his master, "Maybe I should've said "DiMaggio?"
Sylvester does this in ''Peck Up Your Troubles" as he is trying to catch a woodpecker:
Sylvester's sign: Why didn't I think of this before? (starts walking up in mid-air)
Sign #2: Anything can happen in a cartoon!
Tar and Feathers: In one Road Runner cartoon, Wile E. Coyote tries to capture the Road Runner with a tar-and-feather machine. Not surprisingly, Wile E. is the one who winds up tarred and feathered, after which the Road Runner runs up holding a sign that reads, "Road runners already have feathers."
Taxman Takes the Winnings: In the short "The Wabbit Who Came to Supper", Elmer Fudd expects to inherit $3 Million from his Uncle Louie. But when Louie dies, Elmer has to pay an Inheritance Tax, State Tax, County Tax, Defense Tax, Special Tax and Property Tax...leaving him owing the government $1.98.
Team Rocket Wins: Yes, there is a moment in which Wile E. Coyote is successful in capturing the Road Runner. Thanks to Rule of Funny, the Coyote is much...much smaller than the Road Runner when the former captures the latter causing Wile E. to be absolutely baffled as to what to do with the Roadrunner upon capturing him.
There are numerous viewer-created "Coyote Catches Road Runner" clips on You Tube, but this video, culled and composited from Fast And Furry-ous, is by far the funniest.
Elmer Fudd gained the odd victory against Bugs (eg."Rabbit Rampage", "Hare Brush" and "What's Opera, Doc?" (although in that last one, he felt remorse for supposedly killing Bugs, who is only faking it)). After taking a beating against Daffy (and the boxing match referee) in "To Duck...Or Not To Duck," Elmer chalks up a victory at the end.
Daffy Duck, even post-Flanderization had a few spectacular victories to balance his Butt-Monkey role (eg. "Ducking The Devil", "Mucho Locos").
With some assistance from Speedy Gonzales, Sylvester chalks up a win at the end of 1964's A Message To Gracias.
With some assistance from Bugs Bunny, the Big Bad Wolf (from the "Three Little Pigs" story) chalks up a win at the end of 1949's The Windblown Hare.
Shep, the egotistical canine from Chuck Jones' Fresh Airedale, is more Took a Level in Jerkass than villain, although his goal—to eliminate a Scottish terrier who was deemed the city's top dog—would seem evil enough to qualify him as a villain. It goes awry as Shep nearly drowns and the terrier rescues him. But when the terrier collapses from exhaustion, everybody—the press included—fetes Shep as a hero that rescued the terrier.
Used in I Love To Singa. A receptionist receives a telegram from a sleazy deliveryman. She reads it and the camera pans away.
We just received another telegram, Station GOMG. Stop. Your program coming in great. Stop. Think it's fine. Stop. Glad to hear your amateurs. Stop. They're all very funny. [camera pans back to show her continually pushing away the deliveryman as he keeps trying to hold her] Stop! Keep up the good work. Stop! Good luck. STOP! The gang. STOP![she pushes him offscreen and he crashes]
The Television Talks Back: In "Dog Collared", Porky sees a newscast on TV about a missing dog (the same dog that had been pestering Porky the whole cartoon), and anyone who returns it will get a reward of $5,000.
Porky: (amazed) A thousand b-b-b-b-bucks? Announcer: No, five thousandb-b-b-b-bucks!
Once the practice of "That's all Folks!" writing itself out at the end became the standard, there were quite a few cartoons that subverted and/or averted it:
The Major Lied Till Dawn (Tashlin, 1938—the elephant trying to remember something says it)
Porky's Duck Hunt (Avery, 1937—Everything already written out as Daffy jumps around on the letters)
Old Glory (Jones, 1939—it and the Merrie Melodies/Produced by Leon Schlesinger tags simply fade in over the waving American flag on the original print)
The Old Grey Hare (1944, Clampett—titles already in place; card shakes violently after the dynamite Elmer was holding at the iris out explodes)
Coal Black and de Sebben Dwarfs (1943, Clampett—all titles already displayed over animation of the grandmother and child from the beginning in a rocking chair)
A Ham in a Role (1949, McKimson) starts off with a dog taking a pie in the face and strumming his lips idiotically, followed by a static "That's all, Folks!" title card.
The Three Little Bops (Freleng, 1957—an iris out and a simple "The End" on the screen)
Lumber Jack Rabbit (Jones, 1954—all three title elements simply fade in as part of the 3-D effect in which the cartoon was made. At the opening, the W-B shield zooms so far in as if to leap into the audience.)
Rabid Rider (O'Callaghan, 2010—Written on the side of a mountain the Road Runner rides past)
I Tawt I Taw a Puddy Tat (O'Callaghan, 2011—Written on a shirt on a clothesline Tweety flies past)
Daffy's Rhapsody (O'Callaghan, 2012—A card with the phrase written on it appears, then giant bullet holes appear in it. Daffy and Elmer run through them, with Elmer stopping and aiming his gun right at the camera, saying, "Now I'm weally, weally mad." He then brings down his gun to do his Signature Laugh, before bringing it up again and firing)
Several Merrie Melodies films re-edited in the 40s as Blue Ribbon re-releases had "That's all, Folks!" replaced with "The End" in Lydian script over the concentric circles title cards.
The 1967 redrawn edition of The Village Smithy (1937, Avery) has the outline of "That's all folks!" against a red background; a white card is slowly pulled from left to right behind it to cheaply simulate writing itself out (the original print from 1937 has the title writing itself out against a black background). Virtually all other redrawn Looney Tunes either had the Warner-Bros.-Seven Arts closing titles or the spliced-in late 50s That's all Folks! Looney Tunes closing titles.
The first Looney Tune to use Porky in the drum was "Rover's Rival". Looney Tunes would go back to the self-writing "That's all folks!" in 1946.
Completely averted in the "Dork Age" cartoons from 1964 to 1969, where the ending was the abstract WB logo then the Warner Bros.-Seven Arts logo followed by a self-printing "A Warner Bros. (-Seven Arts) cartoon, a Vitaphone (Vitagraph) release."
At the end of Who Framed Roger Rabbit Porky is one of two policemen with back to the camera dispersing the crowd saying "There's nothing to see here, that's all folks!" He turns to face the camera saying "Hey, I like that!" then assumes the classic pose as he repeats the line, sharing the iris-out with Walt Disney's Tinkerbell.
Invasion Of The Bunny Snatchers (1991, Ford, Lennon) has a premature "That's all folks" which Bugs stops so the cartoon can continue. It ends with a very poor computer-animated Porky Pig attempting the drum ending tag—Bugs kicks it out and places the real Porky in the drum for the tag line.
Blooper Bunny (1992, Ford, Lennon) has a quick "That's all Folks!" title card after the Bugs Bunny "special", then at the end after Bugs' final line, we see "That's all Folks!" written by hand on the film tail.
Space Jam (1996) ends with Bugs starting out the phrase but interrupted by Porky, Daffy, the Nerdlucks, and Michael Jordan.
Looney Tunes: Back in Action (2003) ends with Porky's stuttering going on long enough to miss the cue, and then he just angrily mutters, "Go home, folks," after the studio lights shut off.
They Fight Crime!: The Sylvester and Tweety Mysteries, also several original shorts pairing Daffy and Porky as crimefighters ("Rocket Squad," "Deduce, You Say", "Boston Quackie," Daffy solo in The Great Piggy Bank Robbery, "The Super Snooper" and "Stupor Duck"). And good ol' Bugs in "Super Rabbit."
Three Stooges Shout-Out: In what is probably the earliest shout-out of this trope the cartoon "Wholly Smoke" (1938) has three cigars resembling the Three Stooges rise out of a cigar box and each one gives him an eyepoke. ◦ "Hollywood Steps Out" shows caricatures of famous Hollywood actors of the time, including the Three Stooges poking each others eyes in tune to the music.
The Stooges also appear in "Porky's Hero Agency" (1938) indulging in face slaps and eye pokes before Medusa turns them into statues. "Porky In Wackyland" has very loose caricatures of them as a three-headed being occupying a single body. His mother was scared by a pawnbroker's sign.
Time Travel: From 1946's "Mouse Menace"—in less than a second, Porky zips into town and returns with a pet carrier (with a cat inside).
Porky: (to us) A flat tire held me up, folks.
Also seen in "The Pest That Came To Dinner", after Porky calls the exterminator on the phone to come over to rid his house of the termite, after which the exterminator shows up not a few seconds later.
In "The Bashful Buzzard", Beaky tries to wrestle what he thinks is a small lizard out from between some rocks, behind which lie the enormous body of a dragon.
A similar reveal is used in the earlier "Prehistoric Porky" with Porky's pet dinosaur, its terrier-sized head peeking out of a small doghouse while the rest of the body lies behind it.
In "Thumb Fun", Daffy Duck confronts the driver of a tiny car. When the driver steps out, however, he's a seven-foot, 300-pound thug with a tiny head hardly visible atop his broad shoulders.
Title Drop: In "What's Up, Doc?", Bugs sings, what else, his catchphrase.
Also in "Scaredy Cat", Porky title drops the name of the cartoon to Sylvester when trying to convince him nothing's in the kitchen after trying to drag Sylvester in the kitchen once again.
In both "I Taw a Putty Tat" and "Bad Ol' Putty Tat", Tweety Bird himself title drops both of them respectively and they're also his catchphrases.
In "Rabbit Punch", Bugs title drops the name of the cartoon when heckling "The Champ" after the announcer counts down when Bugs is knocked out by "The Champ".
Title Montage: The first opening for The Bugs Bunny and Tweety Show (i.e. the one without the new Darrell Van Citters animation) features clips from old cartoons, including "What's Up, Doc?", "Hot Cross Bunny", "Stupor Duck", "Person to Bunny", and "Long-Haired Hare", among others.
Toilet Humour: The implied bed-wetting scene in "Porky's Badtime Story"/"Tick Tock Tuckered" as well as "Daffy Duck Slept Here"; one of the racing dogs in "The Greyhounded Hare" is named Whizzer (though it can follow that he was named for his speed and not weak bladder).
"The Sneezin' Weasel": The baby chick runs for the bathroom after having castor oil administered to him.
Giant: Hey, wait a minute! Trying to pull a fast one on me, eh? Well, he [Bugs] can't outsmart me, because I'm a moron!
Too Dumb to Live: Elmer Fudd, Yosemite Sam, Marvin The Martian, the Tasmanian Devil, Daffy Duck, in short, Bugs Bunny's enemies.
Oh, and did we mention Wile E. Coyote?
Too Kinky to Torture: Daffy Duck at the end of Bob Clampett's "The Wise Quacking Duck". after getting his feathers shot off and being put in a gas oven, Daffy is somehow alive and quips, "Say, now you're cooking with gas!" while drizzling jus all over himself
Pepé Le Pew on most occasions — the most infamous one being 1953's "Wild Over You," where Pepé goes after an escaped wildcat, despite the fact she keeps beating the tar out of him. (His ending line is proof that "Wild Over You" fits this trope: "If you have not tried eet, do not knock eet!")
Toothy Bird: Most of the birds are at least on occasion.
Traveling-Pipe Bulge: In "Billboard Frolics", a cat traps a dog in a piece of pipe, which bulges where the dog thrashes around inside.
Train Job: How Yosemite Sam gets his introduction in "Hare Trigger". He later tries (unsuccessfully) to rob a train in "Wild and Woolly Hare".
Tranquil Fury: The Tasmanian Devil would occasionally slip into this.
Turtle Island: In The Ducktators a Japanese duck, implied to be Hideki Tojo, places a sign on a turtle, who gets mad and beats him up with said sign (despite that the duck briefly stops him to show a button that reads, "I am Chinese" — a reference to Chinese-American immigrants who were mistaken for Japanese and were put in internment camps because of it).
Un-Cancelled: A few times. The first was in 1953 when WB temporarily closed the cartoon unit for a few months, due to a variety of factors like the 3-D fad; the unit opened a few months later. The next was in 1963 when WB, facing increasingly stiff competition from TV and less theaters running theatrical shorts before movies, shut the cartoon unit down again. From 1964 to 1967, cartoons were produced at De Patie-Freleng instead. In 1967, production resumed at Warner Bros. but only two years later, the cartoon division was shut down for good.
Uncertain Doom: In one Roadrunner short, the coyote requests that the cartoon be ended before he hits bottom, so that his fate remains (technically) unknown.
Uncle Tomfoolery: The reason why there's a collection of cartoons called The Censored Eleven, though there are some WB cartoons with extensive black stereotypes in them that aren't part of this collection, but have been banned from syndication all the same.
A Running Gag involves characters like Wile E. Coyote getting seriously injured and then being perfectly fine in the next scene with no explanation as to how they recovered from their injuries.
Hugo, the Lennieexpyabominable snowman Bugs and Daffy met once in The Abominable Snow Rabbit (1961), ended up melting into a puddle ("He melted! He really was a snowman!") in his first appearance. He ended up inexplicably coming back in all his yeti-like glory in Spaced Out Bunny (1980) and was last seen on the moon, recruiting Marvin the Martian as his new "George".
Hugo: (with Bugs in his grip) Oh boy, oh boy, at last my own little bunny rabbit.
Unrobotic Reveal: In one short, Wile E. Coyote consults a computer to find ways of capturing Bugs Bunny, all of which fail. At the end the computer opens up and out comes...
Bugs Bunny: Of course, the real beauty of this machine is that it has only one moving part.
Updated Re-release: In the TV special "Bugs Bunny's Thanksgiving Diet", one of the cartoons featured is "Rabbit Every Monday". During the scene where Bugs tricks Sam into thinking there's a party in the stove, the big band music and footage from the original cartoon is replaced with disco music and footage.
"To Beep or Not to Beep": Despite all the footage being reused from the TV pilot "The Adventures of the Road Runner", the music is brand new, replacing Milt Franklyn's with Bill Lava's.
