An older gentleman that was a little hard of hearing took his wife with him to the doctor's office so she could help him. A nurse came into the waiting room, walked over to the old couple and in a quiet voice to the husband so other patients would not hear she said "The doctor would like a sperm sample, a urine sample and a stool sample." The old gent turns to his wife and asks "What did she say?" The wife replies in a loud voice, "They want your underwear!"
