RN2B...er RN!

A male patient is lying in bed in the hospital, wearing 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 may elevate his blood pressure and heart rate from
worry 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!'

The man pulls off his oxygen mask, smiles at her and says very slowly,
'Thank you very much. That was wonderful, but listen very, very
closely...
