April Fools Pranks

Hi, I am looking for some good pranks to pull on a coworker next week. His last day with us is actually on April 1st so we figure it has to be extra special. Just to give you a bit of background, he is in his 20s and has a great sense of humor. We work in an office setting. As in he has his own office as well as a bunch of other people.

So hopefully a bunch of you have great ideas for pranks.

Thanks!!!

Here are some things that have been done to me. If you have access to his car keys, move it somewhere else in the lot. A sandwich with styrofoam in it. Don't actually let him eat any though. Get in a trash can, if you have the big ones and jump out.
We did this to a friend at his house, if you know how to get in. Take some of his clothes and stuff them, put boots on the stuffed dummie's feet a baseball hat or something on some stuffing for a head, and set it in a chair ( we also put a beer bottle in it's hand. Scares the heck out of you when you walk in the door.

Mess up his computer screen <ctrl> <alt> <down arrow key> Make it go upside down. That's pretty tame; I think I can even do that at my office (accounting firm -- can you say a bit stifff?!

That's all I've got.. I"m tired. Going to bed now.

Ooooh very good! Some great ideas! It's a great thread, I can never come up with the right prank to play on my honey. Hope we get more post in this thread. Going to definitely be keeping an eye out for more ideas

Oh I really like that computer one. He will laugh. I might have to try it on a couple of people. Keep the prank ideas coming.

LOL, one year my entire team called in sick to our manager. All except the lead and she set up an emergency "meeting" for him. We were all waiting in the conference room when he walked in "April Fools!" It was hilarious, he actually flicked us all off and walked out of the room. LOL

Ok, I just did the unpside down screen thing to see if it worked - Uh, how do I fix it? Lol!!!

Ok, figured it out! Lol I feel dumb :S
