Bloke in intensive care, oxygen mask, drips, etc. attached. The nurse is making him comfortable, and asks if there is anything else she can do for him or if he wants anything else.

He asks her 'Are my testicles black?"
She panics and tells him that's not her job, but she'll get the Matron.

Matron comes in and asks "Now, what can I do for you?"

He asks again, "Are my testicles black?"

Matron sighs, lifts the sheets, looks, palpates and replies "No, they are pink and soft and look fine. Why?"

He removes the mask and asks again, "Are my test results back?"

I should have tried that one.
