A man in a hospital bed wearing an oxygen mask over his mouth and nose. "Nurse" he mumbles "are my testicles black?" The nurse raises his gown, holds his manhood in one hand and his testicles in the other. She takes a close look and says " There is nothing wrong with them sir!"
The man pulls off the oxygen mask, smiles at her and says very very slowly " Thanks for that , it was just wonderful but listen very , very closely and carefully................... Are - my - test - results - back !!!!
