Yearly Physical

[dobry4u]

An old man 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."
