For a Rorschach Test, a psychiatrist shows a guy a series of ink blots and asks him what he sees. The man answers, in series:

"A man and a woman making love in a park."
"A man and a woman making love in a boat."
"A man and a woman making love at the beach."
...

At the end of the test, the psychiatrist looks over his notes and says, "It looks like you have a preoccupation with sex."

"Me!?" the man demands, "You're the one who keeps showing me the dirty pictures!"
