Yep - been there, done that in the wacking your shin category. I've got a few fading scars from the old platforms on my MTB, but in an amazing feat of talent, after a TT 2 weeks ago I did the same thing, but with the SPD pedals on my road bike. That one actually ended up being the worse I've had, there are still some big gashes on my shin that are healing up. Definately going to leave a scar.

I've never done the pubic bone hit on a bike before, but did during a very spectacular horse wreck where it hit into a saddle horn. Hurt for days, and I never want to experience that one again.
