Looney Tunes

Looney Tunes is an animated show that has been referenced to in Happy Tree Friends many times.

Lumpy Alone: The Cuddlus Rabbitus & Lumpus Moosus scene makes a reference to the Road Runner cartoons.

Petunia's First Word: When toddler Cuddles hears Petunia say her first word, he exclaims "Sufferin' sucatache!", Sylvester's catchphrase.

Cuddles' Inner Child: The scene where Lumpy dumps the trampoline of a cliff is a parody of the Road Runner cartoons.

The HTF Files: Marvin the Martian appears in a line-up of aliens.

The Itchy & Scratchy & Poochie Show: Cashew claims he did the voice of the Road Runner, but only was able to do one meep as the studio doubled it up.

Petunia's Sax: Michigan J. Frog appears as the mascot of The Warner Brothers Network.

Brother's Little Helper: Pop says to Cuddles "That's the end of your Looney Tune, Drugs Bunny!"

There's Something About Marrying: After Cuddles and Toothy's attempt to get a seedless watermelon dropped on Kaleidoscope by using a can of Duff Beer as bait backfires, Kaleidoscope says to the boys "Now, as the Road Runner said to the coyote..." then jumps up ala the Road Runner saying "Meep-meep!" and zips off with a ricochet sound effect.

The Last Of The Red Hat Mamas: The rabbit at the Easter celebration is called Hugs Bunny, a reference to Bugs Bunny.

G.I. Oooohhhh: The scene where Lumpy is getting chased by the predator drone is a parody of Looney Tunes. Lumpy fools the drone by reading a newspaper, dressing like a female drone, using soap suds to disguise himself as an old man in the bath (which prompts the drone to hold up a sign saying "Sorry, sir") and then sneaking around, hiding behind objects and luring the drone into a dark cupboard full of TNT and when the drone lights a match to see, it explodes. The monitor that the Army colonel is watching this on then says "That's All Folks!"

Apocalypse Cow: One of the chickens is named "Leghorn", a reference to Foghorn Leghorn.

Lumpy The Father: The Itchy & Scratchy cartoon is titled "Ain't I a Stinger?", punning one of Bugs Bunny's catchphrases.

The Scorpion's Tale: A Coyote and Road Runner appear in the desert in a parody of the Road Runner cartoons.

Dial "C" For "Candy": Nutty killing Lifty & Shifty with a rock is a parody of the Road Runner cartoons. He then runs off with a "meep meep".
