Reminds me of a joke that I heard from an art teacher once.

Okay, this guy goes to see a psychiatrist who starts by saying he'd like to get an idea about his client's mind by giving him a little test.

The psychiatrist drew a straight line on a piece of paper and asked, "What do you see in this?"

The man said, "A person standing naked."

The psychiatrist drew two vertical parallel lines and asked, "What do you see in this?"

The man said, "Two people taking off their clothes."

The psychiatrist drew two horizontal parallel lines and asked, "What do you see in this?"

The man said, "Two people having sex.

The psychiatrist said, "I think I have some insight into you now, you seem to be obsessed with sex," to which the man said, "Hey Doc, you're the one drawing the dirty pictures!"
