re: #233 Khal Wimpo (the extinguisher of tiki torches)
Shit! Many years ago, I saw a grizzled IT graybeard raise a (then cutting-edge) PC-AT up and perform that maneuver.
I just thought it was frustration. The fact that there is actually a *reason* for doing so is a total bonus for me …
The phrase “percussive maintenance” was invented specifically for maneuvers like this. Also, the hand-slap or karate-chop to the CRT monitor (or the occasional hard disk drive).
