Beavis and Butt-Head don disguises after they get a death threat from Earl.
- Asleep in Class: Beavis and Butt-Head are asleep at the start and wake up when Van Dreissen is teaching about photosynthesis (which he mentions isn't even on the test).
- Accidental Misnaming: Earl thinks the pair are Beaver and Butt-Plug.
- Even Evil Has Standards: Earl takes issue with how another student interrupted the lesson on photosynthesis.
- Paper-Thin Disguise: As "Crevis and Bung-Head" the duo do nothing beyond wear glasses and hats. It fools nobody.
