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 his 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 for me. Are my testicles black?"
Concerned he might elevate his blood pressure and heart rate from worrying about his testicles, she overcomes her embarrassment and pulls back the sheets. She raises his gown hold his manhood in one hand and his testicles in the other.
She looks at them very closely and says "Sir they look fine there is nothing wrong with them"
The man slowly pulls off his oxygen mask, smiles at her and says very slowly. "Thank you very much that was wonderful. Now listen very closely."
