Black Testicles

[Prelude: I got this from from my Mom. BOY, was that interesting!]

A white 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 hospital gown, holds his penis in one hand and his testicles in the other hand, takes a closer look and announces, "They look white to me, sir!"

The man removes his oxygen mask and says very slowly, "That was really nice, but listen very, very closely: Are...My...Test...Results...Back?"
