If it's not running on PSU, I spin round in my chair. It's what I do when I wait for my PC to boot. You can see the obvious implications of spinning in a chair holding a GP2X with a PSU lead sticking out the side.
...and... snap! psu-socket wrenched out of gp2x.
swears
drops gp2x to reach for cable
crunch! spinning chair slides across floor and crushes gp2x
leans over to rescue the injured gp2x
crash! chair falls over and topples into PC, inadvertantly hitting the 'eject' button on the cd-drive which was burning a disc and had reached 98% complete.
cd-tray ejects, knocking over foolishly placed mug of coffee.
