Jumping 173ft off of a beautiful waterfall. I did get knocked out when I hit the water and completely lost my memory for about five minutes after being pulled out of the water. If I had not been pulled out of the water by two people who I respect dearly I could have died.

Meanwhile, in the student newspaper at the School of FAIL...

It's kind of like Napoleon Dynamite, but far more painful.

Just a little work on the calculation of the jump height and parachute timing.
