A drunken man was wandering around the parking lot of a bar, bumping into every car and 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.'

'So how does feeling the roof help you?' He asked the drunk.

'Well,' the drunk replied. 'MY car has two blue lights and a siren on the roof!!'
