Tim walks into a bar and sees his friend Peter slumped over the bar.
He walks over and asks Peter what's wrong. "Well," replies Peter, "you know that beautiful girl at work that I wanted to ask out, but I got an erection every time I saw her?"
"Yes," replies Tim with a laugh. "Well," says Peter, straightening up, "I finally plucked up the courage to ask her out, and she agreed."
"That's great!" says Tim, "When are you going out?"
"Well I went to meet her this evening," continues Peter, "but I was worried I'd get an erection again. So I got some duct tape and taped my penis to my leg, so if I did, it wouldn't show."
"Sensible." says Tim.
"So I get to her door," says Peter, "and I rang her doorbell. She answered it in the sheerest, tiniest dress you ever saw."
"And what happened then?"
"I kicked her in the face."
