An retired old police officer goes to the doctor for his yearly
physical, his wife tagging along.

When the doctor enters the examination
room, he tells the old man, "I need a urine sample, a stool sample and a
sperm sample."

The old man, being hard-of-hearing, looks at his wife and
yells, "What, What did he say? What's he want?".

His wife yells back, "He needs your underwear!"
