I outraced two guys who were on mountain bikes when I was on my Rollerblades. The best part? We were offroad.
Climbed a 30+ foot rock wall in ~13 seconds.
Ate 11 hot dogs at one sitting. I only stopped because I didn't want to taste another hot dog, not because I felt full.
Did a hard stop on my mountain bike with my first set of v-brakes (pulled dat front brake like a fool), ended up going over the handlebar and somehow landed squarely on my feet.
Part of the 3 man FTC robotics team that won third place at the world championship.
Been on a billboard, the side of a bus, in several ads, and part of some video campaign (in the video my brother and I got baseballs signed by former Cardinals player Scott Rolen).
Never fully broken a bone; the closest I've come is a small fracture in my pinky.
Achieved 20/10 vision on a vision test.
Might post more later if I think of anything...
