A Police officer pulled over a driver who'd been weaving in and out of the lanes. He approached the car window and said, 'Sir, I need you to blow into this breathalyser tube?
The man immediately reached into his pocket and produced a doctor's note. On it was written: 'This man suffers from terrible asthma. Please don't make him perform any action that'll leave him short of
breath.
The officer said, 'OK then, I need you to come and give a blood sample.' Straightaway, the man produced another letter. This one read: 'This man is a haemophiliac. Please do not cause him to bleed in any way.'
So the police officer said, 'Right, I need a urine sample then.' The man produced a third letter from his pocket. It read, "This man Supports Aberdeen Football Club. Please don't take the piss out of him".
