Erection problems

Dave walks into a pub and sees his friend Paul slumped over the bar. He walks over and asks him why he's looking so down.

"Well," replies Paul, "you know that beautiful girl at work that I wanted to ask out but got an erection every time I saw her?"

"Yes," replied Dave with a laugh.

"Well," says Paul straightening up, "I finally plucked up the courage to ask her out, and she's said yes."

"That's great!" Says Dave, "when are you going out?"

"Well, I went to meet her this evening, 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 Dave.

"So I get to her door," says Paul, "and I rang her bell. She answered it in the sheerest, tiniest, sexiest dress you ever saw."

"And what happened?" asks Dave.

Paul slumps back over the bar again. "I kicked her in the face."
