Well, I haven't pulled that stunt but the dumbest thing I ever did with my boat was to forget to remove the back tie-down straps before putting my boat into the water. I looked up in the rear view mirror and saw that my boat was no longer straight behind the truck but had rotated to off to a 45 degree angle. The boat had floated the trailer up off of the ramp and the whole deal was swiveling around on the ball hitch.
