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?“
