And another medical joke for today

Just got this one in from Fiona, my lovely Financial Advisor here in the UK ... great lady who knows her onions when it comes to investing money and unlike me, does not mix metaphors....

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 four hour operation.

A young nurse appears 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 privates and jiggles them around a bit, takes a close look and says,"There's nothing wrong with them!"

The man pulls off his oxygen mask and says very slowly,"That was very nice..but listen very, very closely: Are...my...tests...results...back?

Red faces all around....or were they?
