Well that doesn't mean you can't play office pranks.
Here are some you can try at work! Hours of great fun!
Put a piece of onion or a clove of garlic inside the mouthpiece of
a phone. Give it some time for it to fester and build up a strong
odor. Then call them and keep them on the phone for as long as
possible.
It is always a good habit to lock your computer before heading off
for coffee or a smoke. When someone forgets and leaves a Word
document or an email open, type a single word somewhere in the
text. f*ck or so will do nicely. Theyll never notice and send it
out.
Get a hold of someone's cell phone and change the greeting banner
to say "NO SERVICE". Many cell phones have greeting banners on them
that you can personalize to say whatever you want them to and it
stays on there when you're not using your phone. Also, when there
is no service where you are, most cell phone companies have a
banner that pops up on your screen saying "no service".
Take a can of non gel shaving cream, and put it in a freezer. When
it is frozen remove the bottom of the can and put it in co worker's
drawer. When it melts it expands and explodes all over
everything.
Go into MS Word or similar program on co-worker's computer, and add
an entry to the AutoCorrect feature. This is a very simple prank
that will send the novice user into a frenzy. Configure the
AutoCorrect option to replace the word "the" with the phrase "you
suck!". They will usually panick and start scanning for
viruses.
Take clear tape and tape the underside of the mouse. Make sure you
take the sticky end of the tape and apply it to the bottom of the
mouse so it locks the ball in place. The victim will most likely
check the connections in the back, reinstall drivers, reboot, etc.,
before they realize what has happened.
Do a "Print Screen" of the user's desktop, and then paste the image
from the clipboard to a photo program, and save the image as a
bitmap. Then, set the 'snapshot' of their desktop as the actual
desktop wallpaper. (You'll have to hide the Windows status bar, and
move all their desktop icons into a folder, which you can hide
conspicuously in the corner or something.) The user will see their
desktop as always, but everything on it will appear to be frozen
when they try to click on it...sending them into a rebooting and
virus scanning fit!
This will mostly only work with people with very little PC
knowledge. Stick in a floppy in there floppy drive. They will be
unable to boot up windows until the disk is out. This is fun to
watch.
Try to find a very obnoxious CD laying around. Preferably a reggae
or rap CD. Pop it in their CD ROM. Put up the sound full blast by
double clicking on the volume control on the bottom right. On
normal configurations the audio CD will autoplay when windows first
starts up. The person starting up there PC in the morning will
definitely be embarrassed.
This is for that special person you just cant stand in the office,
the one who talks on the phone all day with their
boyfriend/girlfriend and gets personal e-mail all day. Go into
their e-mail and change their defaults to automatically "blind
carbon copy" their boss or supervisor. Heads will roll!
Change the coffee in the office coffe maker to decafe. Wait about
three weeks(or untill you think everybody has gotten over their
caffine addiction)and switch to expresso!
Try "password securing" someone's screen saver. First I suggest
changing the screen saver to "scrolling marque" and inserting your
own word or phrase, "Mr. Jones (president or supervisor) eats SHlT"
or something to that effect.
With someone who is on the phone a lot during work - This works if
you have phones that the handset comes apart. Take the handset
apart and put scotch tape over the mouthpeice inside. They can
still be heard, but they have to talk loud to be heard. The next
day take it off, and put it in the earpeice. Usually they will be
yelling to the other person on the line the next day, and won't be
able to hear them. When they complain about the phone, and get a
replacement, do it on the next phone. After about a week you will
notice the calls to be down considerably.
My absolutely most favorite prank I have saved for last. It is so
simple to do and yields such nice results. Simply pop out the 'm'
and 'n' key on someone's keyboard and reverse the two. Any flat
tool will work. Just pry it with little pressure and they will
easily come right off. Then just sit back and watch the
confusion.
