Holy Crap! Your computer is possessed! No matter what you do, your keyboard isn't responding! Weird messages scroll across your screen.

I wish you wouldn't pound my keys so hard. Its making me....angry.
That's exactly how your coworker or school mate will respond when he/she finds what YOU'VE typed.
this is my entry for the April Fools contest. Please, please vote for me. I need that book. I want to make it april fools day every day at my school. Help me with my cause!

Step 1: What You Need.

-2 cubicles or desks in a computer lab that are adjacent, as in across from one another.
-a keyboard
-a friend with a good sense of humor (or not, an enemy will work just fine)

Step 2: Setup the Prank

1. While the worker or schoolmate is out for lunch or not in yet, crawl under your cubicle or desk until you face the back ports of their computer. You can do this if you two are juxtaposed to each other by rotating their hard drive until the back ports are facing you.

Step 3: Setup Prank Cont.

1. Unplug their keyboard input cord
2. Plug in yours

Step 4: Go Crazy

DO WHAT EVER YOU WANT!!! This prank works great and makes me laugh until i cry every time. If you want to have some extra fun, try to keep a straight face and do this again and again. I've seen people take their computers to get them checked.
