Pixar Shorts/Funny

Presto

 * The whole thing. Pixar does Tex Avery - by way of Portal.

Jack-Jack Attack!
"Kari: "HIII! I'm Kari! I'm the BABY-SITTER!"."

"Syndrome: "I was gonna have something for "Baby-Sitter," but then I'd be walking around with BS on my shirt.""
 * Syndrome explaining that the 'S' on his costume stands for "Sitter."


 * Kari just... sitting there, having become, if not particularly accustomed to Jack-Jack, at least capable of dealing with whatever power manifests at a moment's notice, e.g. extinguishing him when he turns his flame on.

Dug's Special Mission
"Alpha: Now, your mission is to sit on that rock. Dug: Okay! (jumps to the other rock causing the rock Alpha, Beta, and Gamma are on to tilt. The three dogs begin running around trying to even the balance, but the rock falls and the dogs fall, screaming) Dug: (jumping from rock to rock) Find the bird, find the bird! (Alpha, Beta, and Gamma follow, screaming as the rocks fall and Alpha goes down with one) Alpha: Ow! I am hurting!"
 * All of it, as Dug repeatedly acts as The Millstone for the rest of the pack. "Alpha, the rock moved!"
 * Notable examples:

George and AJ
"Carl Fredericksen: "Afternoon, boys!""
 * The two eponymous characters being in Jaw Drop mode for more than a full day!
 * The many ways the houses scram (Cats, slingshot, hovercraft, drill, oxygen rocket)
 * Carl's Dynamic Entry in his fucking-huge zeppelin !!

Luxo Jr.

 * The end. After the smaller desk lamp accidentally deflates the ball he was jumping on, he runs off-screen, with the bigger lamp looking after him...only to recoil in surprise when the smaller lamp comes back with an even bigger ball. The other lamp looks at the audience and shakes its head like it's saying, "He'll never learn."

Lifted

 * The poor alien. Just his facial expressions.
 * I'm sure everyone in the theater was in hysterics when
 * A small one, but the little alien pushing his teacher out of the way, leaving a large handprint which starts slowly sucking back into shape like gelatin. If memory serves, Pixar built a new software simulation engine just for that gag.
 * Then there's the moment when the alien just completely gives up in frustration and starts hitting all the switches.

For The Birds

 * The tiny birds. Seriously, they all sound like squeaky toys.
 * When all the littler birds are mocking the big, goofy one when they first see him.
 * Then comes the appropriately karmic comeuppance. Nekkid birdies!

Knick Knack

 * EVERYTHING.

Day and Night

 * EVERYTHING.
 * Just hearing all those silly sound effects made me laugh.
 * At the end of Day & Night, when

Mike's New Car
""It's like we've unleashed the panther.""

"Sulley: (cell phone rings and he answers it) Hello? Mike: PUSH THE BUTTON!!!!!"
 * The part where the car.
 * "Hey! Don't just sit there! Push the button!"


 * Combined with Crowning Moment of Heartwarming: The DVD Commentary for Mike's New Car. Hearing the kids' interpretation of what exactly their parents do for a living is both funny and adorable.

Toy Story Toons: Hawaiian Vacation
"Woody: Ride like the wind, Bullseye!" Ken: Ride like the wind, Buttercup! Buttercup: Okay, get off me."
 * "We removed the poop from the kitty litter."
 * Chuckles the Clown leading the luau, reading his lines completely deadpan.
 * What about the part with Ken and Barbie pretending that they were deep-sea diving? The part with Ham even switching the tv that they were swimming in front of from a tranquil underwater scene with fish to a shark submerging out of the water, making Ken and Barbie freak out made me die laughing.
 * There's also the part with Mr. Pricklepants having the three Pizza Planet aliens audition for his latest production. Initially, he thought that the first two aliens' performances were mediocre or dreadful, but he liked the third one's great emotion. The cincher?
 * And let's not forget at the end of the short where Ken and Barbie stepped outside in the snow in their winter clothes to share their first kiss before walking off the front step of the porch and into the deep spot of the snow. The scene after the credits even showed Woody and the others using a blow dryer to defrost Ken and Barbie from the ice block that they were frozen solid in.
 * Horseback riding.
 * Horseback riding.

"Ken: I thought we were staying at a resort? (Jessie puts up sitcky note with the word "resort" on it over the word "motel") Potato Head: Welcome to the Bonnielikeoke resort!"
 * The Bonnielikeoke motel.

Cars Toons

 * "I'M STOCK!!!"

Your Friend the Rat

 * The intro to the Black Plague part. "It doesn't go from rats and darkness to rats and death skulls!"

Toy Story Shorts: Small Fry

 * The entire performance of Jane Lynch as a support group moderator, and pretty much every toy in the group.

Partly Cloudy

 * EVERYTHING. God, that poor, poor stork....
 * The reveal of the stork's head being completely covered in porcupine quills. But what really sells it is the nervous little laugh that accompanies it.

Mr. Incredible and Pals
"Frozone: You ok'd the rabbit, didn't you?! Mr. Incredible: I HAD NOTHING TO DO WITH THE RABBIT!"
 * This exchange in the commentary:
