Used Car/Bounty Hunters - S8-E9
Continuity mistake: In "Used Car", when Beavis and Butt-head first approach the car, it's in between two trucks, a white one and a brown one. At the end, the spot where the car was is now between a green car and the white truck.
Butt-head: Beavis, I told you I wasn't gonna let you touch the remote anymore. Now, give me that, buttknocker.
Beavis: No, way. And stop calling me buttknocker.
Butt-head: Give it here before I kick your buttknockering ass.
Beavis: Stop calling me that, Butt-head! Stop it.
Butt-head: Buttknocker.
Beavis: Shut up, Butt-head! Shut up! I'm gonna kill you, Butt-head! I swear to go God, I'm gonna kill you.
Butt-head: You and what other buttknocker?
Trivia: Mike Judge once received an angry phone message from a fast-talking man. The man seemed to be complaining about "Beavis and Butthead", although he mentioned a "Porky's butthole". His voice later inspired the voice for Boomhauer on "King of the Hill".

Question: Why did Mr. Van Driessen only give Beavis and Butt-Head one phone?
