1. Cups

This is a classic, well known prank, but if you haven’t heard of it, here it is. Fill many cups, say halfway, and put them around something that is commonly used, like the Bathroom, or a workspace.

2. Chair Pins

Put some thumbtacks on the chair of your victim, and watch as the antics ensue.

3. Stuck Door

If your victim has their own room, make sure they will be in there for a while and glue the door shut.

4.  Jello Snack

Get some jello mix, and your victims mouse and Keyboard keys. Put them both in separate plates of jello, and put it back on their workspace.

5. Surprise Mess

If their door opens into the hallway, put some dust, and such at the bottom of the door. When it opens, the air suction will pull it in and leave the room filthy.

6. Keepin you at work

If their door opens into the hallway, and they have a door handle(I have another one for your knobs) take some duct tape, and tape under it, through it, and every which way on the door frame, and when they try and open, they will be stuck.

7. Slippery Knob

Melt some butter in the microwave, and put it on their door knob. Make sure you have enough on there to keep them busy cleaning it.

8. Slipping

In the bathroom, butter the sides of the toilet. When someone sits, they will slip in.

9. Funny looking Coffee

Put enough butter in the Coffee to give it a yellowish tinge.

10. Microwave

Fill ever bit of the microwave with butter, and have it on for 5 minutes. By then, people will smell it, wondering what it is, and find the buttery microwave.

11. Spam

Collect all of the paper trash from your office building, and fill it into the cubicle of someone who is away.
