The infamous Beavis and Butthead. Such a good show. A show about two best friends, and we know they are best friends because in one of the Christmas episodes Butthead is shown a world were he was never born. Nobody knows who Butthead is. Not even his best friend Beavis. When Butthead is returned to the world were he is in fact born, Beavis knows who he is again. Butthead says that the world would, “suck”, without them. This is how we know they are indeed, best friends.
