Where do I start.... We'll start with the most recent.
I was installing all new coaxial cable in the house. I needed to run several cables in the (finished) ceiling across the top of a basement bearing wall. I opened a small portion of ceiling and uncovered blocking between the joists directly above the wall. I figured it was odd but whipped out the drill, big ol mean 16'' long 1" auger and started going at it, until the bit caught, Oh Well, I thought.. I put the drill in reverse, but it was hung up that way too. I couldn't pull, the bit was lodged. I wiggled it around and saw light streaming in... I thought, THERE SHOULD NOT BE LIGHT THERE!!
Then it donned on me when I around the corner to go up the basement steps. I saw my bit all wound up in the carpet that was
on the first riser. SH!T!!! It is very easy to get turned around, even in your own home.
