|A drunken man was wondering around the parking lot of a bar, bumping into then rubbing the roofs of the cars.|
The manager comes out of the bar and stops the guy.
"What the heck are you doing ?" he asks the drunk.
"I'm looking for my car, and I can't find it." he replies.
"So how does feeling the roof help you ?" asks the puzzled manager.
"Well," replies the drunk earnestly, "MY car has two blue lights and a siren on the roof!"
