Here's your sign!

I was helping by buddy change his serpentine belt on his van. I had to get to part of the belt true the wheel well so we jacked up the front, I always use jack stands for safety. I ask my friend to apply the emergency brake and we went to work. I was underneath holding the retched while he tried to brake the bolt loose. With the force of trying to remove the bolt he pushed the van off the jack right on to the jack-stands. If the stands went there I would have been crushed!!! I said to him, "DID YOU SET THE EMERGENCY BRAKE???" his response was "oh, I forgot!"

So, I got my sign for not checking the E-brake my self.
