Three things, two truthful...
I used to sleep walk and one night my dad found me out side, about to jump off the top of a flight of concrete steps leading up to the front of the house thinking I was about to dive into a swimming pool. (I was having a dream). Had he not stopped me I might have done some serious damage.)
I once bit down into a styrofoam swimming kick-board thing, held it there and jumped into the pool...The board floated, I didn't...And it cracked four of my teeth off with it.
When in Monaco we went to the Grand casino and I had a go at roulette. I ended up winning 1000 Euro but got greedy and ended up losing it all again, and the 50 Euro I started with.
