Obviously first step was accidental while trying to look at a water leak.
Once I realized it I immediately screamed in pain and attempted to pull my foot off. However, after it popped off I lost my balance and tried to put the foot back down and avoid the board. Driving my heel down I slammed it right back down on the board again.
At that point many words only spoken by a drunken pirate was said. I pulled my foot off again, only to fall back on a pile of stacked hardy board siding. As my butt hit that it was pinched between to pieces. Yes, my butt is sore also and more inappropriate words were screamed.
