Any one got any good april fools pranks I can play at work.

This idea made me grin when I read it...

one of my mates from work told me another mate was killed in a car crash on holiday. hilarious... i didn't beleive him, told him to STFU, and the boss was well pissed of with him for his sick joke ha ha ha

Get some car window glass from breakers, Pick someone at works car lower driverside window and scatter glass on ground beneath.

Jack the car up and take the wheels off

or if they have locking wheel nuts

jack the car just enough that the drive wheels have not got any grip but not so it looks like they are off the floor
then stand back and watch them get confussed when the car don't pull away.

Apparently if you soak the inside of the toilet roll, take it apart and twist it back together it looks like a little poo. Might be good for a little "deposit" on someone's desk/chair/lunchbox

Find several paper hole punch tools in the office, empty the contents (all those small pieces of circular paper). Then carefully deposit them all in someone's car within the heater grills. Set the fan to full and aim the vents at the driver.
When they first start up the car... Whooossh ! A flurry of annoying bits of paper which takes ages to vacuum up!
Harmless !

So what did you go with and did it work?
