"Drunk and Stoned" joke

A guy was driving when a policeman pulled him over. He rolled
down his window and said to the officer, "Is there a problem,
Officer?"
"No problem at all. I just observed your safe driving and am
pleased to award you a $5,000 Safe Driver Award. Congratulations.
What do you think you're going to do with the money?"
He thought for a minute and said, "Well, I guess I'll go get that
drivers' license."
The lady sitting in the passenger seat said to the policeman,
"Oh, don't pay attention to him - he's a smarty-pants when he's drunk
and stoned."
The guy from the back seat said, "I TOLD you guys we wouldn't get
far in a stolen car!"
At that moment, there was a knock from the trunk and a muffled
voice said, "Are we over the border yet?"
