Paddy, being plastered after a night in the pub, driving home.

Suddenly, Paddy had to swerve around a tree ... and another one ... and another one. It went on like that for a good while, til someome rang the cops, who finally pulled Paddy over.

Says the Cop "Jeez Paddy, you are driving like a maniac, what's wrong with ye?"

Paddy, pointing at his windscreen, replies "But Searg, can ye not see all them trees in the middle of the road?"

Says the Cop "Out of the car. Now. That's your feckin air freshener"
