An old man had a doctor's appointment and was very hard of hearing so he took his wife with him to help. When they got into the examining room, the Doctor told the old man to take off his shirt.

The old man turned to the wife and shouted, "What did he say?" and the wife got closer in his ear and yelled, "Take your shirt off!" The old man nodded and took his shirt off.

The Doctor then asked the old man to tilt his head back so that he could have a better look down his throat.

The old man shouted, "What?" and the the wife got closer to his ear and yelled, "Tilt your head back and open your mouth." The old man nodded and tilted his head back.

When this was all over, the Doctor said, "OK, now all I need is a urine sample, a stool sample and a semen sample.

The old man yelled, "What?" and the wife got closer to his ear and yelled, "The Doctor wants your underpants!"
