Place it right after the reveal that the toilet roll is empty, then follow it with a toilet flush and a record scratch to close the bathroom gag and move the edit on.
About this sound
This five-second clip has Beavis in his Cornholio persona urgently demanding toilet paper for his bunghole in a strained, nasal voice. The dead-serious delivery of such a crude request feels frantic, absurd and instantly derailing, turning an ordinary moment into surreal comedy. It comes from Beavis and Butt-Head, Mike Judge's animated television series, where Cornholio's search for toilet paper became a defining joke.
