Work can be very boring (what am i saying! replace "can be" with "is"!)but I have come up with a plan to make the day & effort worthwhile, prank effort that is!
You'll need: Deoderant (Spray), a Lighter & a victim.
This prank works with cubicles, lock all the cubicles except one (placing out of order signs works) Now, spray deoderant surronding the toilet (not the toilet) and make a trail to near the door (where you will be) make sure you spray a lot or it aint gonna work. Now fing your victim's coffee and put a bottle of laxative in it. Wait untill they run into the bathroom, then follow. As soon as their sitting & shiting get your lighter & light the spray. RUN LIKE HELL. They are gonna think the bathrooms on fire!!! I did it on a co-worker Brenton & he filled a "Co-Working Complaint".... what Bullshit.
To make the worker more scared, spray the Devil symbol on the door. Its Judgement Day for a Co-Worker!
