Uh huh huh huh, I'm a deer!
- The movie's plot literally kicks off with Butt-Head using a mechanical leg to punt Beavis square in the 'nads, which propels him across the room. Beavis' scream is loud and high pitched enough to destroy everything in the gym that has a glass apparatus, even Van Driessen's glasses.Butt-Head: We kicked science's ass!
- The boys are chosen for the mission in the first place because they are obsessed with using the space docking mechanism to simulate sex. They then control a robotic arm to make it look like the booster rocket is masturbating.
- Serena tells Beavis, who thinks he's going to score with her, that 256 men, 49 women, a Russian dog, and a chimpanzee have been to space. He interprets it to mean that she Really Gets Around, and then some!
- Beavis and Butthead's large-brained Alternate Universe counterparts, while similarly amused by lewd double-meanings, have a rather broader vocabulary than "uh, huh-huh." The following exchange is a Call-Back to the trailer announcing the movie, in which Butthead points out that Beavis said "mount" in saying "Paramount+".Smart Butthead: You said "mount," Smart Beavis.Smart Beavis: Yes, their primitive language has two meanings for that word, yes.Smart Butthead: Humorous, quite jocular.Smart Beavis: Very droll and whimsical, yes, yes.
- The whole white privilege scene. During the scene where a gender studies professor and her students try to spell out the definition of white privilege, a woman of color is interrupted by a white man who is clearly trying to demonstrate how progressive he is. Afterwards, Beavis and Butt-Head take advantage of their "white privilege", commit vandalism and shoplift in full view of retail staff. It isn't until they hijack a police car that the cops even think of punishing them.
- After consuming an ungodly amount of methamphetamine (or similar pills), Beavis turns into his alter-ego, Cornholio. When he, in true Cornholio fashion, demands more TP, the other prisoners agree with him that they need more TP. They start a riot, and actually get the toilet paper they wanted.
- Beavis and Butthead's respective fantasies of how "scoring" will change their lives.
- Beavis dreams of flying with Serena astride a winged unicorn - which is then revealed to have Butthead's face and hair.
Unicorn Butthead: Uh, huh-huh. I'm a deer.- Butthead, in a fur coat and dollar sign medallion, enters a club. Adoring groupies ask if he'll score with them.
Butthead: {looks at camera with raised eyebrow} ...Indeed.
