Beavis and Butt-Head (1993)

Beavis: Hey Butt-head, is it normal for the inside of your bunghole to itch?
Butt-head: Beavis, it's not even normal to ask.

Trivia: Mike Judge not only received complaints about "Beavis and Butthead", but also some death threats, including a poem about the writer wanting to kill him.

Citizens' Arrest - S7-E12

Question: Why does the police officer call this a citizen's arrest? Beavis and Butthead were more like hostages in the situation. They never caught/subdued the robber.
