Some years ago, I worked as a drywall hanger. Our crew got on a new construction job, and started in the biggest room hanging the ceilings. I had to run to the truck for a tool, and had to step around a carpenter that was in my way. When I came back through, I swear to god what I witnessed could only be seen in cartoons.
There was a carpenter who was cutting a hole in the floor for the basement stairwell. He sat on the floor, and cut all around himself. Seriously! he literaly sat on the part to be removed and remained there until the plywood broke and he went down with the ship.
Everybody all came running to see what happened, and it was what a reckneck would call "self evident". The foreman took one look through the hole to the basement floor and said, "You've gotta be $#$%^* me! I said, "Nope, seen it with my own eyes. Wiley E. Coyote couldn't have done it any better...."
