A man is lying in a hospital bed with an oxygen mask over his mouth. A beautiful young nurse arrives to sponge his hands and feet. “Nurse,” he mumbles from behind the oxygen mask, “are my testicles black?”

Embarrassed, the young nurse replies, “I don’t know, I’m only here to wash your hands and feet.”

Struggling, he again asks the nurse, “Are my testicles black?” Finally, she raises his gown, holds his penis in one hand, holds his testicles in the other, takes a close look, and says, “There’s nothing wrong with them!”

The man pulls off his oxygen mask and replies, “That was very nice, but, are my test results back.”
