ludicrousity

I need ideas for pranks to pull at work. I can't hurt anyone, and I can't do anything to prevent work from being done. I *am* friends with the computer people. I know who I want to get, too.

The guy who sits next to me is Danny Forget (for-jay).

So far, I plan to switch his big, new, flat monitor with the old, small, fat monitor on the last student's desk. I'm going to post a "Welcome to the desk of Danny CantRemember" poster at his desk. I'm going to put piles of paper labelled "Urgent" on his desk. I'm going to label the fun stuff on his desk with random names of people we work with. I know he'll figure out who did it. I know he'll get me back.
He leaves early, and I leave late, so at least I'll have time to prep on the 31st...

I also want to prank my dad, but I don't think the jello in the toilet trick would bug anyone but me.

PLEASE COMMENT WITH IDEAS!!!!
