Beavis and Butt-Head Season 7 Episode 9 - Head Lice Episode Title:Head Lice.Episode Description:Beavis and Butt-Head are scratching their heads in class. Buzzcut tells them that they have head lice, and sends them to the school nurse, who finds them in their hair. Instead of following the nurse's advice, the duo break open a bug zapper and touch the element in order to kill the lice—electrocuting themselves in the process. Beavis also has pubic lice, so he puts his genitals into the zapper, electrocuting himself again.
