April Fools

[Starburst..x]

Okay I know some people think it's immature but hey it's a laugh!

I work with quite a few guys and there's been some pranks going around the past few weeks e.g decorating the inside of peoples cars with silly string and so im in need of some decent ideas to get them. However I dont want anything that's going to cause damage/upset/offense.
The other day they were going to get a condom then fill it with hair conditioner and leave it in my bag or car for me to find, so Im needing pranks along this level if anyone has any decent ideas.
A few of them have cars if this helps? ;)

Hide a strong cheese somewhere in their car?

[Chippiewill]

Find some roadkill, stick it in an oven at festering temperature, chuck it in their car.

I remember at school I put a note in every form's register saying that school photos were that day. Boys weren't that bothered but the girls went insane. Haha.

Why not the old orange up the exhaust?

Let a stink bomb off inside their car, thats worse than what they did to you. :P

[Jessicrawrr]

hide cheese, or something that goes mouldy, or something that's mouldy and hide it in the car.
