This morning I found a bottle of pills I put up in a safe place where nobody would steal them and couldn't find them for the last 4 months.
My favorite gotcha was when I couldn't find my small vise grips. Looked and looked nowhere to be found. I was fuming because I was convinced the kids lost them. A few days later I was under my truck that had been out of commission for several months while I rebuilt the transmission. My small vise grips were clamped to the exhaust stud holding the exhaust pipe up.
