There’s a wonderful Gahan Wilson cartoon which I cannot find. A boy and a girl are sitting on a couch. The girl’s shirt is off, and she’s got a neutral expression on her face. The boy is recoiling in horror and fear, because her torso is a demonic face, contorted with fury, with her boobs as big eyeballs, dark pupils where her nipples would be. The demonic face is snarling at the boy, “I told you not to DO that!”
