Sometime ago I stumbled across a "Trunk Monkey" video. The video -- part of a series -- involved a chimpanzee living in the trunk of your car. When you had certain problems, you pushed a button, and the Trunk Monkey solved the problems.
The video involving the car thief almost caused me to drown in Dr. Pepper.
The full series of Trunk Monkey videos can be found here. Be forewarned that the site has a picture gallery in which the occasional young lady in a bikini and a Trunk Money doll will show up. Personally, I'm all in favour of young ladies in bikinis, but your boss and/or Human Resources Department may not see things my way.
Anyhoo, I had filed Trunk Monkeys away as an amusement, until today, when I discovered that our troopies have apparently been referring to the rear gunner in gun trucks and hard-backed HMMWVs as the "Trunk Monkey".
And there are even (unofficial) Trunk Monkey Patches.
Oh, I'm going to have to get one of those.
