Off The Cuff, I'm Going To Mexico

Three Mexican minors had been driving a pick up truck on a remote Californian highway when they were stopped by a Border Patrol agent, who suspected them of smuggling drugs. The Agent handcuffed them and put them in his patrol car while he searched the truck for marijuana. Unfortunately, he left his own car running, with the keys in the ignition, before leaving the three boys alone.
They, of course, promptly grabbed the steering wheel and drove the car straight back across the border to Mexico.
Well, you would, wouldn't you?
Mexican police located the patrol vehicle in a remote agricultural area near the border.
