A guy goes in to see a psychiatrist. The psychiatrist tells him to lie down and asks him what the problem seems to be.

The guy says: "Doc, I think I'm gay."

Psychiatrist: "Why do you think that?"

The guy says: "My father is gay."

Psychiatrist:"Well, just because he's gay doesn't mean that you're gay."

The guy says: "Yeah, but my brother and my cousins are gay."

Psychiatrist: "Really? How interesting! Well, tell me, isn't their anyone at all in your family that sleeps with women?"

The guy says: "Oh, sure."

Psychiatrist: "Well, who?"

The guys says: "My sisters."
