Beavis and Butthead are doing a fundraiser, where they have to sell chocolate bars for a class visitor named Mr. Candy. The pair end up buying each others' bars and eating them themselves. However, since they only have enough money between them for one bar ($2), they trade the money back and forth.
The next day, when he finds out that all of the bars are gone, but they only had the $2, Mr. Candy threatens them, as he would lose his job over this. Just then, Coach Buzzcut comes in and threatens Mr. Candy for allegedly harming a student. When Mr. Candy retaliates against Buzzcut, albeit pathetically, Buzzcut then proceeds to beat the crap out of Mr. Candy, much to the amusement of Beavis and Butthead.
