A male patient is lying in bed in the hospital with an oxygen mask
over his mouth and nose and still heavily sedated from a 4-hour
operation. A young nurse appears in his room 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 'johnson'
in one hand and his testicles in the other hand, takes a close look and
says, "There's nothing wrong with them."

The man removes his oxygen mask and says very slowly, "That was really nice, but listen very, very closely, "Are...my...test...results...back?"
