Don't know if this is the appropriate forum for this thread. Oh well.
In line with the sticky about hilarious ways you tap someone, post your humorous grappling injuries (not standard stuff like hyper extensions etc.)
Mine: I've broken (apparently) my right big toe at least once and injured it several other times. The first injury came from rolling over my head from a standard triangle to a mounted triangle on a guy with about 30-40 pounds on me when I was a one year white belt. It wasn't quite set and both of our weight was supported by my toe. I've since repeated this but with shorter recovery times. The first time my toe hurt bad for two-three weeks.
Barely avoided further hilarity the other day when under n-s the guy grabbed my gi and ear. Luckily he readjusted his grip before spinning to an armbar otherwise I wouldn't have to worry about cauliflower anymore.
