Three blokes are driving around, drinking beers
and having a laugh when the driver looks in the
mirror and sees the flashing lights of a police
car telling him to pull over.

The other two are really worried. "What are we
going to do with our beers? We're in trouble!"
"No," the driver says, "it's OK, just pull the
label off your bottle and stick them on your
foreheads, and the bloke pulls over.

The police officer then walks up and says, "You
lads were swerving all around the road back there.
Have you been drinking?"

"Oh, no, officer," says the driver, pointing to
his forehead, "We're trying to give up, so
we're on the patch."
