Yes, we've done this before.
In fact, we've done everything before.  
 
<--I've broken a thumb, my nose, and my right ankle.
Thumb: Goofing around with a friend, we were pretend fighting and I lost my balance, put my hand out to stop the fall and my thumb jammed into the ground.  The pain was exquisite.
Nose: Walking dog on icy driveway with hands in my pockets to keep them warm.  I slipped and went face first onto the ground.
Ankle: Jumping down stairs.
Coincidentally, all these stupid injuries happened when I was in high school.  I swear, people reach the height of their stupidity during their teen years.  I was certainly no exception.
