The personal computer is a strange and powerful entity, capable of bringing great joy. Just as often, you probably want to chuck the damn thing at the wall because it doesn't work right. If you want to pull a prank on a friend that will really upset them, messing with their computer is one of the best ways to do it. This hilarious video will show you how to do three great PC pranks quickly and easily, including changing the contrast on the monitor and pretending to edit websites using Javascript. If you have a little computer saavy and are looking for a new way to trick your fellows, look no further.

From the creator:

CODE 1:
javascript:function Shw(n) {if (self.moveBy) {for (i = 35; i > 0; i--) {for (j = n; j > 0; j--) {self.moveBy(1,i);self.moveBy(i,0);self.moveBy(0,-i);self.moveBy(-i,0); } } }} Shw(6)

CODE 2:
javascript:document.body.contentEditable='true'; document.designMode='on'; void 0

HOW TO MAKE THINGS NORMAL AGAIN:
To undo the? the mac color-invert press the same buttons again. To undo the mac contrast change hold command+option+control and hit "," (comma) until it's normal. To undo the Windows color-invert go to: Start, Control Panel, Accessibility Options, Display.? Then de-select "high contrast mode" -- depending on what you're running, it could also be in Control Panel, Appearance. You can see other funky contrast options there, too -- be sure you pick the right one or your computer might look like Windows 95 LOL XD
