What you see is not what you get
Superman is flying over the city one day and sees Wonderwoman sunbathing nude on top of a building, with her legs spread wide open. He says to himself "Mmmm, I sure would like to get some of that wonderpussy! I bet I could do it so fast, she'd never know what happened." So he flies down, does his thing, and he's gone, all in the blink of an eye. Wonderwoman asks "What the hell was that?". The invisible man replies "I don't know, but my a-hole sure is sore!".
