Man in hospital bed wearing oxygen mask over his mouth. "Nurse", he mumbles. "Are my testicles black?" Nurse raises his gown, holds his penis in one hand & his testicles in the other, ...she takes a close look & says, "There's nothing wrong with them Sir." Man pulls off the oxygen mask, smiles at her & says very slowly, "Thanks for that, it was lovely, but listen very very carefully. "Are -my -test -re -sults -back?"
