A truck driver sees a girl about to jump off a bridge so he stops.

"What are you doing?" he says.

"I'm trying to commit suicide," she says.

"Well, before you jump give me some oral sex."

So, she does.

After she's finished, the trucker says, "Wow! That's a wasted talent. Why are you committing a suicide?"

"My parents don't like me dressing up like a girl."
