Make a computer appear broken.

You can use a nail file to pop the keys off the keyboard and switch them around. People that need to look at the keys to type will get fucked up, but people that type by instinct won't be bothered at all.

Also, put a small piece of clear tape on the bottom of the mouse, over the light or ball. That way, when the mouse moves, it won't respond, and the person will think something's fucked up, but the mouse will be plugged in and appear normal.

Shitty pranks, but they may elicit a laugh or two.

Best broken comp....

Try this.. this is really simple.

Go to Command Prompt and type:

/Format C:

or something like that.

It won't work. Windows won't let you if it's the windows partition.(wich i'm sure to be the case with C: )

So tell me, how did you know it was a Windows partition?

Open computer, locate any of the following connectors, yank them out, close case, done.



To "repair", plug back in.

Windows is the only OS that label root as C:, and it only does that to the disk/partition it is installed in.

That sounds hilarious. Lots people don't know how to type properly.

put a magnet on your hard drive

If you're really willing to put effort into it, make a dummy tower and put a couple bricks in it to replicate the weight. If you're really going for a realistic effect, set some LED lights up in it.
