Two truck driving brothers are taking a driving test, and the instructor asks, "You`re driving the truck and you`re at the top of a mountain and your brakes go out. You notice an accident at the bottom of the mountain, what do you do?"
The trucker replies, "The first thing I do is wake up my brother."
"What good is that going to do?" the instructor asks.
The trucker replies replies, "In all of the years we`ve been driving he ain`t never seen an accident like the one we`re about to get in to."
