The Problem: how to open a bottle of beer without getting off your ass.
Just now, I sat down at my laptop with a beer. I am in the corner of a room where I paint pictures. Dang, I think. I need a bottle opener.
The set of car keys has a bottle opener attachment, but that set of keys is in the pocket of my jacket on the other side of the house.
But there are paint can openers and those have bottle openers on the back end. No. I can not see one laying in the clutter of canvas and dust.
Ah. But here in the junk drawer alongside the laptop is an old American Camper utility blade. On it is a survivor bottle opener. Dang! I broke the bottle opener last time I sat at the computer without a bottle opener. Now it is useless.
Ah. In my wallet there is a credit card sized combination saw tool for basic brute level utility purposes. In that is a slot that opens bottles.
Problem solved.
I think there is a Boyscout badge for this.
