An elderly man is at the doctor's office for his annual checkup. The nurse leads him to the examining room, gets his height, weight, blood pressure, etc. and tells him the doctor will need a urine sample. a stool sample and a sperm sample. The man tells the nurse that he's hard of hearing and asks her to repeat what she said. The nurse tells the man once again that the doctor needs a urine sample, a stool sample and a sperm sample. Once again, the man doesn't understand what she's saying and asks her to repeat it once more. In a much louder voice the nurse says "the doctor wants your underwear".
