Racing is life... anything else is just waiting.
Ballast.
That actually happens. I was on one of those prop commuter planes several years ago (20-30 passenger plane) and they actually did ask this fat woman to move to the front of the plane to rebalance it. She probably weighed a good 2 bucks and change and there were a lot of people sitting in the back. But it was still a rather awkward moment when they pulled her to the front.
Unless I HAD to be some place at a certain time, my favorite thing to do was volunteering to take the next flight if they overbooked. Hey, they'll give you a free round trip ticket if you take a later flight. I still have three or four round trip ticket vouchers (anywhere in the U.S.) from NorthWorst, if they haven't expired already.
