A man in hospital wearing an oxygen mask over his mouth.
'Nurse' he mumbles 'are my testicals black?'
The nurse raises the mans gown and taking his penis in one hand and his testicals in the other gives them a good examination. 'No sir there is nothing wrong with them' she says
The man pulls of his oxygen mask and smiles at the nurse and says 'thanks for that it was lovely but listen very carefully, are - my- test- re-sults- back?'
