After playing paintball with some friends, I was riding on the tailgate of my friend's pickup truck. When he drove through a little mud, he momentarily lost traction. He gave the engine more gas, and the truck surged forward after regaining traction. The truck's bedliner was very smooth, so I didn't move quite as fast as the truck did.
I knew that I was going to slip off, so I threw my stuff into the lap of the guy sitting next to me. Thankfully, the truck only got up to a little over five miles an hour. I dropped into a backward ukemi roll and ran to catch up to them. The look on my friend's face when I sat back down was pretty comical.
Often it's in ways that surprise us, but aikido definitely works!!
