Fender moons a Sweeper, when his back hatch falls off, spilling spare parts. The Sweeper takes offense (or detects the sudden loose parts clattering around) and starts backing toward him, while he frantically tries to collect everything.
"Oh, they brought it back." The capper to the entire crazy Crosstown Express sequence.
Ratchett begging. "No wait please listen to me, you cant do this to me. This job is my LIFE! It means everything to me! You don't KNOW WHAT I'VE DONE TO GET HERE !! THE LIES I'VE TOLD, THE LIVES I RUINED!!!!!"
"...This isn't helping me."
Ratchet: No wait, please can't I just make one more heartfelt plea?
Bigweld: Okay, what did you wanna say?
Ratchet: (knocks Bigweld out with intercom mic) THAT! (pause) Oh my Gosh, I'm as crazy as my mother. *beat* *hits him again*
Aunt Fanny thinks that the armpit farting contest was a REAL farting contest, and sets off her Fartillery full blast. Hilarity ensued.
Fender trying to tell the others (though Rodney already knows) who is behind everything.
Fender: Hey, guys! The sweepers! They're rounding up all the outmodes! Not them, us! And you'll never guess who's behind it all!
Rodney Copperbottom: Ratchet.
Fender: Go on, guess. Come on, I ran all this way in cha-cha heels! Go ahead, take a stab!
Rodney Copperbottom: Ratchet!
When Rodney sarcastically remarks an angry mob will soon show up after Crank goes missing, one actually does run past. This causes Fender to want Rodney to make another "prediction".
Fender: Wow! That was great, psychic friend! Now say, Money should be falling from the sky. Say it. [sobbing] Say it!
Every damned time Ratchet Screams Like a Little Girl. Special mention goes to when Bigweld rolls into his office and yells his name. He screeches, drops the intercom mic and scrambles into Bigweld's chair. Never fails to get a laugh.
Diesel imitating Piper when she yells at Jack Hammer
Ratchet and his father:
Ratchet: Bye dad! Ratchet's dad: Bye son! Good luck with your dastardly plan!
"I've told you over and over, 'Don't talk to strange men.' Thank you, Manuel."
"I talk to you. Who's stranger than that?"
Everything with Bigweld's Ball, especially their ruse to sneak inside, and Fender hitting it off with Loretta Geargrinder.
Loretta: Anyone dressed as badly as you, must be an eccentric billionaire.
