Any ideas of a practical joke to play on co-worker? (Harmless)

Take a little black shoe polish and put it on his receiver on his phone. That one works wonders!

Have his car towed.

Change the keyboard properties. I remember someone saying you could put the shutdown command in the autoexec file, don't know what the command is though.

If you want another food prank, there's nothing quite like the stench of a couple day old seafood. Save your snow crab and shrimp scaps, leave a little meat on for good measure

Put his car up for sale in a classifieds section of a newspaper for real cheap, and put his office phone # on the classified, so everyone calls asking about his car for sale so he would be like WTF.
hehe, my senior class did this to my principal and his 66 GTO.

Hey Sluggo,

How do you go about reversing the keys on the keyboard like that?

That would be sweet and I have the perfect candidate.

Food is always good. Fish on a peice of paper over the weekend.

Or use that leftover jack-o-latern. Smash it up and set it on his desk over the weekend. Make sure you leave it outside all week so as to rot nicely.

This prank should get the guy back

In response to kantonburg: Just remove the keys from the keyboard and re-place them where the other was. To remove a key, wedge a pointed object (if the object is too sharp, like the point of a sharpened pencil, it may not be strong enough) under the key and pry it up. I think this works for all modern keyboards, since keyboards are damn impossible to clean without removing the keys.

Oh I thought he meant you could actually change the location of the M and N key (reverse them) not physically but actually when you type. Now that would really mess with people.

get several of those "car" air fresheners that you normally hang from the rear view mirror and hide them in his/her desk (tape 'em under a drawer, under a desk blotter, ect); soon the scent becomes too much.

put a light coating of vaseline on the ear piece of the phone so that the first time they use it, their ear gets coated.

alternately raise and lower their seat so that they either feel like a midget or jam their knees into the desk.

fill all their desk drawers with stryofoam peanuts

collect all the paper punch out dots and put them in their desk drawers; a definite nuisance.

a little bit of peanut butter on the handles of their desk drawers

after they leave for the day, clean their desk off and put everything in a box then put a new screen saver on that welcomes someone named "Bob" or "Cindy", ect.

if they leave their coat in a community area, tie a knot in one sleeve then wad up a bunch of masking tape and lodge it in the other sleeve. Finally, fill all the pockets with the paper punch-outs.

You can get a bit nastier. If he's married and packs his lunch, carefully slip in a pair of women's panties in his lunch box for his wife to find.

good luck and have fun.

There are programs which can do that kantonburg, but switching the keys is easier, and most novices who still look at the keyboard to type will get really messed up.
