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