The joke is that Beavis and Butthead don't have the slightest clue as to what a breakfast burrito is. (A breakfast burrito is eggs, cheese, sausage, peppers, onions, and tomatos or salsa etc. wrapped in a tortilla so it looks like a burrito). I think McDonald's invented it, but I'm not sure. But our boys don't know what to expect, so they like spit it out and stuff.
