Amuse me with decent practical joke stories. I'll start, as I remembered this one today.
A mate of mine works with a bunch of lads who are a bit.. well.. laddish. Consequently there's often a bit of porn knocking round the office.
One of the guys wasn't happy about it, and would often moan about the girly-mag thing.
So one day the guys plastered the whole of one side of his car with porn as a laugh.
That day he finished work early and got in his car, not seeing the pornofied passenger side and drove off.... to pick his daughter up from school, unaware of the wall of hardcore porn he parked up directly facing the school gates.
*= actually a mate of a mate but that kills the story a bit.
