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 ofthe 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!’.
