Extremely! Especially if you try to curl your toes back under your foot.
I've done it twice. Once was on one of those $%#-%^#%$@ wheels on a bed frame. The other time was in high school. Some field hockey sticks had appeared from somewhere and our coach split us into two teams and armed us. The ball came out of the madding crowd. I had been hanging around the fringe of the mayhem, hoping to at some point in the future father a child, and it came directly toward me. I took off, shoving it along it front of me. Another player (could have been a teammate for all we knew about the game) couldn't catch me, so he just swung his club down in front of me, hitting me in the big toe.
