Here are some ideas from http://www.shanemcdonald.com
Ring your friend before he / she goes to work and say ” I’m so sorry to hear you got fired ! ” – Act surprised they didn’t know yet.
Wet a tissue with milk and run around holding the tissue to your eye pretending you stuck your pen in your eye, when somebody comes close, squeeze the tissue to make the Milk spurt out all over the place.
Place Cling-film over the toilet seat – an old prank but a good one !
Ring your friend and pretend to be from the local GPs office. Tell them they might have Newcastles Disease ( a chicken disease – don’t tell them that ).
Sign somebody up to an embarrasing email newsletter.
Go around the office and tell random people that a particular person (e.g. your friend) wanted them to drop over at 11am – they will be surprised when 50 people drop around to their cubicle at once.
Start a rumour that your company is being taken over and loads of staff will be made redundant. Watch the onset of panic.
Put loads of Pencil (scribble and really build up the graphite) on a piece of paper and then rub around the eye and upper jaw. Then go around the office and say you were hit beacuse you didn’t get the report in on time.
Advertise your bosses job in the local newspsper – (Great if you want to get fired !).
Get a universal remote control and turn the volume up on all the TVs in your local TV shop, while standing nearby. Try be covert so you can keep doing it.
If you are a manager or have employees under you, send people looking for made up items such as the dehydrated water, the hydraulic cement humidifier, the double sided transperencies, a fallopian tube, the blunt knife, a glass hammer.
If you work in a restaurant, tell all employees that due to new fiar trade regulations, each serving of fries or chips must contain exactly 257 pieces.
During lunch, say to your friend, “Sorry to hear about your partner, (pause) I suppose you had to find out about the affair sooner or later – the whole office knew about 2 months ago.”.
Use a 3M Post-it notes placed underneath someones’s computer mouse – ensure that it covers the ball or the optical sensor on the bottom. When they go to use the mouse, it won’t work! On the 3M Post-it simply write April Fool!.
Get access to another person’s office, cubicle or room, and move the entire contents of it to another location or even just outside the door. Another variation is to turn all objects in the room the opposite direction.
Do a few replacements … Substitute Gravy instead of coffee granules !
If your last one out of the office, empty multiple packs of Jello or Gelatine into the Toliets – the result next morning will be fun !
Break a chilli pepper and rub it a few times on mugs and cups .. adds spice to the daily cup of coffee.
If you have a digital camera, take a picture of the toilet, then plug in your digital camera into a PC or TV (using TV-out) and get the picture on screen. When you see people coming out of the toilets, start laughing out loud and pointing. The person will come and see the picture and think you saw them in there !
Switch the signs for Mens and Ladies toilets … watch the fun !
