Mess with your doctor's mind #1

Urine sample required? May I suggest that 4 hours before the sample is... delivered... you take 2 multivitamin pills, eat half a kilo of asparagus & wash it down with a litre of beetroot juice.

That should do it.

Do not be alarmed by the colour & odour of the sample. Tell your doctor that you fasted as per instructions.

But confess to the jape before surgery occurs.
