Did you know that if you have 20 sheets of drywall in the back of a half ton pickup truck and the guy who loaded them says, "Don't worry, they won't shift."......they will?
Did you know that they will shift at the worst possible moment?
More specifically, Did you know that they will shift right when you accelerate to turn onto the access road to the highway? (with LOTS of traffic headed your way)
Did you know that if you have a 4 wheel drive, you can whip into the grass, turn around, jump out, load all 20 sheets back into the truck before someone runs over you?
Did you know that this would NEVER EVER happen to me, because I would NEVER EVER do something that stupid?
