I actually fell through the floor today. I was installing a new floor and when I hit the nail tool my foot slipped on the new flooring. It slid right into an open heating vent in the floor and down through the cieling below. My leg went through to past the knee and was trapped in the tight hole. Luckily I didn't break any bones but pulling my leg out was like getting a tight ring off a finger with a big knuckle. I have several very nice bruses, swollen bits, and assorted raspberries.
The celing has a giant hole in it.
Pix soon!
