Animaniacs sketch featuring Slappy Squirrel in a parody of the famous milk commercials. A young Slappy drinks buttermilk as she stands next to a big bodybuilder. As she drinks she grows into a tall and curvy adult; however the bodybuilder looks bored and ignores her. After a few more gulps Slappy ages into a bitter old squirrel. Harboring resentment for being ignored by the muscleman she blows up the bodybuilder with a bomb; the announcer says, "Buttermilk, it makes a body bitter”.
