A male patient is lying in bed in the hospital, wearing an oxygen mask  over his mouth and nose. A young student nurse appears to give him a  partial sponge bath.

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

He struggles to ask again, 'Nurse, please check. Are my testicles black?'

Concerned that he might elevate his blood pressure and heart rate from worrying about his testicles, she overcomes her embarrassment  and  pulls back the covers. She raises his gown, holds his manhood in one hand    and his testicles in the other. Then, she takes a close look and says, 'There's nothing wrong with them, Sir. They look fine.'

The man slowly pulls off his oxygen mask, smiles at her, and says very slowly, 'Thank you very much. That was wonderful, but listen very very closely,
'Are - my - test - results - back?

gotta love it  

I have been known to say a thing or two to the nurses when I am over medicated.
