A policeman in Dublin pulled over a driver who had been weaving in and out of the traffic.
He approached the car window and said "Sir I need you to blow into this breathalyzer".
The man reaches into his pocket and produces a doctor's note.
On it was written: "This man suffers from chronic asthma. Please do not make him perform any action that may leave him short of breath".

The policeman said "Okay, then I need you to come and give a blood sample"
The man produced another letter.
This one said: "This man is a haemophiliac. Please do not cause him to bleed in any way".

So the officer said: "Right, I need a urine sample then".
The man produces a third letter from his pocket.
It read: "This man plays Rugby for England, please don't take the p155 out of him"

Well done Jonathan, that’s a much more PC punch line than the one I know

If I'm right which I'm often not, that joke finished - "don't take the p155 out of spastics" but you don't call them spastics now do you.
