A man goes to his doctor and admits that he has a sexual problem.‘I just can’t get it up for my wife any more,’ he says.‘Don’t worry, Mr Williams,’ says the doctor. ‘Bring your wife in and I’ll see what I can do.’The couple come in the next day and the doctor asks the wife to remove her clothes. Then he asks her to turn around and jump up and down. He turns to the man.‘You’re fine,’ he says. ‘She didn’t give me an erection either.’
