First off your video shows a waterboarder already up not how he got up on the board with only one hand. Second the bone in your shoulder area that breaks is the collar bone which I broke when I was a teen and is very painful. Third did you diagnose your "broke" shoulder or did an actual doctor? Fourth if you indeed broke your collar bone you didn't have very good friends if they actually let you be duct taped up and continue to waterboard. if you indeed saw a doctor and put your arm in a sling. Lastly, again you can fool some of the people some of the time but not all of the people ever. You can push your little fairy tale if you want to just don't expect everyone to believe it. Others have had broken bones and worse and know what's believable.

Yes, you were wrong
Now it's that my friends should not have let me do it.
You analysis is that the guy in the video can flip AND land with 1 hand but could not possibly get up on the board with 1 hand.
Hint: That flip is 100x more difficult than getting up on a Wakeboard.
Maybe if you got out of your Mom's basement and go out in the world you could actually try Wakeboarding.
It's Wakeboarding, not waterboarding.
Waterboarding is a torture technique.
I've have the X-Rays.
