What is the dumbest way you’ve been injured?

Trying to make a very short turn on a long-forked chopper. It didn't end well but I recovered from my embarrassment and injuries.

I broke my arm doing cartwheels off the couch. It looked like I had a second elbow in the middle of my forearm as it was bent at a disgusting angle. I still remember that horrid snapping sound. Yuck. I don't remember any pain though, I think the adrenaline prevented me from feeling it until the next day.

I crashed my bike into someone else going like no miles an hour. But it was rainy and slippery and I injured my leg in the process.
