So this guy is being evaluated by a psychiatrist. The psychiatrist shows him an inkblot and asks, "what does this look like to you?"
"Sex," the guy says. So the psychiatrist shows him another one. "That looks like sex too," says the guy. He shows him a third inkblot. "Yeah, that's definitely sex."
"Sir, it appears that you have a sexual fixation," says the psychiatrist.
"Well, at least I'm not the one drawing the dirty pictures."
