Man in hospital bed wearing an oxygen mask. "Nurse," he mumbles, "Are my testicles black?" Nurse lifts up his gown, holds his willy in one hand and his testicles in the other. She takes a look and says "There's nothing wrong with them sir." Man pulls off the oxygen mask, smiles and says very slowly "Thanks for that, it felt lovely, but this time listen very carefully.... Are-my-test-results-back?!"
