A man is lying in bed in the hospital...

A man is lying in bed in the hospital with an oxygen mask over
his mouth. A young nurse appears to sponge his hands and feet.

"Nurse", he mumbles from behind the mask, are my testicles
black?"
Embarrassed, the young nurse replies, "I don't know, I'm only
here to wash your hands and feet".

He struggles again to ask, nurse, "are my testicles black?"
Finally, she pulls back the covers, raises his gown, holds his
member in one hand and his testicles in her other hand and takes
a close look then say's, "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?"
