Here's a joke:

Paddy the famous Irishman is driving home after downing a few at the local

Pub. He turns a corner and much to his horror he sees a tree in the middle of the road.He swerves to avoid it and almost too late realizes that thereis yet another tree directly in his path. He swerves again and discovers
that his drive home has turned into a slalom course, causing him to veer
from side to side to avoid all the trees.
Moments later he hears the sound of a police siren and brings his car to a
stop. The officer, approaches Paddy's car and asks him what on earth he was
doing. Paddy tells his story of the trees in the road when the officer
stops him mid sentence and says, "Fer Chris sakes, Paddy, that's yer air
freshener!"
