WALL•E, in the escape pod, patting the seat next to him as an invitation to EVE.
And then his exploits trying to get the pod to stop. The thing looks absolutely ridiculous as a result of all the buttons he pushed.
In the trailer: "Seven hundred years into the future, mankind will leave our planet, leaving Earth's cleanup in the hands of one incredible machine." Cut to WALL•E smacking himself in the face with a paddle ball.
M-O jumping off his guide line, just so he can get to do his job. He prepares for it like he will blow up if he leaves the line, but all he gets is a little buzzer. It's his little evil-like laugh that sells this moment.
As well as WALL•E's reaction to it. You can't blame the guy, another inch and this would've been a much shorter movie.
WALL•E kicking and wiggling his feet and hands as he's being carried to a pen in the defective robots ward.
The way the Steward robot says the word "wrong".
GO-4 getting kicked through the window during the Captain's fight with AUTO - and landing just short of the pool.
EVE's little tantrum during her hunt for plant life after getting stuck to a ship's magnet. Resulting in another mini-nuke explosion and a domino rally with beached ships.
WALL-E (after crushing dirt): TA-DA!
WALL•E getting impatient with M-O's incessant cleaning, so he deliberately spreads some muck from his treads on M-O's face.
In a deleted arc, EVE was the one to get initially shocked by AUTO, and WALL•E saves her from being sucked out of the ship. We also get interaction between WALL•E and the two WALL•As that's genuinely hilarious. After getting their attention,, WALL•E uses his trash compacting ability in an attempt to get them to let go of EVE. One of them picks up the resultant cube, and their headlights suddenly take on a "D'awwwww" expression. Then one of them gently pats WALL•E's head as though to say, "Sure thing, kiddo; you'll get to our level someday."
During a brief elevator ride to the escape pods, Wall-E points out a warning on the screen cautioning all on board about himself and EVE. The latter promptly shoots the screen. Wall-E quietly backs up, scrunching up.
The Steward bots saying "HALT!" to the defective robots 2-3 seconds after they all stopped.
The Fashion Robots, and how.
Even AUTO has his moments of funny. Whenever he says "NOT POSSIBLE" or "NO" is just hilarious.
After defeating the police-like robots, one raises up, only to be smacked down by one of WALL-E's crew members.
