Guido's pit stop is without a doubt the Crowning Moment of Awesome for this film. The reaction of Chick Hicks' pit crew is priceless - they drop their mustache grilles. "Peet stop."
Lightning muttering to himself about his failed use of Doc's advice.
Lightning: "Turn right to go left"...Guess what? I tried it, and you know what? This crazy thing happened - I went right! Lizzie: You keep talkin' to yourself, people will think you're crazy. Lightning: (sarcastically) Thanks for the tip. Lizzie: What? I wasn't talking to you.
Harv buttering up Lightning:
Harv: And it is such an honor to be your agent that it almost hurts me to take ten percent of your winnings. And merchandising. And ancillary rights in perpetuity— anyway, what a race, huh, champ?
And later after Harv finds Lightning:
Harv: "You can't buy this kind of publicity! I don't know what you need me for! That's just an expression, by the way, you signed a contract."
What really sells this moment is his change of tone, mid-sentence. At first it's loud and hammy, then it's all serious and quiet, with no warning.
"AND MY NAME'S NOT CHUCK!" Even better is that his character is listed in the credits as "Not Chuck".
Comes up again in the mini-biography collection you can unlock on the Blu-ray. Actually most of the biographies are pretty funny.
This exchange:
Mater: I know this might be a bad time right now, but you owe me fifty two thousand dollars in legal fees.
Lightning: What?
Mater: *Nods*
This exchange between Fillmore and Sarge:
Fillmore: "I'm telling you, man, every third blink is slower."
Sarge: "The Sixties weren't good to you, were they?"
Made even funnier via Word Of God stating that the animators did, in fact, make every third blink a little slower than the first two.
Chick: Hey, McQueen, that must be really embarrassing. But I wouldn't worry about it. Because I didn't do it!
The utter contempt for the Fourth Wall displayed in the credits where Mack comments on John Ratzenberger's voice in Cars versions of several other Pixar films.
Lightning's Freak Out when Van and Minny quickly flee Radiator Springs, while he's stuck to Bessie, flailing around:
Lightning: Don't leave me here! I'm in Hillbilly Hell! My IQ is dropping by the second!! I'M BECOMING ONE OF THEEEEEEEEEMMMMMMMMMM!!!!!!!!!!!
The very final scene after the credits, where Van and Minny are lost in the desert.
Cars 2
Really, Mater provides pretty much all the Funny in this film.
Mater gets some drinks for Lightning at the free bar in Japan. Those who tried their first "pistachio ice cream" knows what's coming a mile away.
Sushi vender: My condolences.
The scene where Mater actually freaks out after seeing a car with headlights for eyes in Paris.
What made this scene is that this is seemingly a reference to the decision to avoid that sort of character design during development of the original Cars as it made characters look like "snakes".
He tries to crash Lightning's and Sally's date at the Wheel Well by posing as a waiter. He even tries a drink at one point, hates the taste, nonchalantly sips it back out into the cup, then almost serves it to Lightning!
When Finn asks Mater if Gremlins are considered lemons, he replies "Is the Popemobile Catholic?. Becomes funnier when we later see that said Popemobile is riding in another popemobile.
Before the race in Italy when the Italian car is talking to Lightning about how he misses his mom when he's over seas.
Francesco: But now we're in my home, and my mom's right there! Hi! *Camera pans to show his mom in the crowd*
During his knighting ceremony Mater realises he hasn't yet made the proper introductions, leading to the following:
While tearing through Radiator Springs on his new jet engines, he comes across the car he towed in the beginning of the movie. He tows him to the shop, hooking him so fast he pulls him right out from under the dust he'd accumulated.
