A elderly man is in an hospital bed

An elderly man is in an hospital bed wearing an oxygen mask over his mouth.

‘Nurse’, he mumbles.

‘Are my ball black?’

Nurse raise his gown, hold his weapon in one hand and his ball in the other.

She take a close look and says ‘there nothing wrong with them sir’.

Elderly man pulls off the oxygen mask, smile at her and says very slowly,

‘Thanks for that, it was lovely but listen very very carefully, are-my-tests-re-sults-back?’
