Funny tricks at the office

Our little human wrecking ball is hard at work.
This would be a funny trick to play on a coworker.
Have Alex take all of the tissues out of the box, then shove them back in. It's irritating when you grab the first tissue, and it rips, with only a tiny shred of a piece in your hand. Then you grab it again, and the entire box of tissues comes out.
This is right up there with attaching all of said coworkers paper clips together.

Don't tell BFF, but when I used to work for her at a certain hippy grocery store, (rhymes with Ralfalfa's), I used to get on the intercom and page myself to the break room.
