So you work in a data center with a raised floor, and things are going slow.... Here's some things to liven up your day. I'm not responsible if the boss doesn't think this is as fun as you do.

1. Lift a tile, turn it upside down, and put it back. Act innocent when someone asked what happened, and mumble something about plenum gremlins. Even more fun is watching people trying to lift the tile, since tile lifters don't work on the rough underside.
2. Remove a tile in a strategic place. Best exercise of this one requires a good imagination. Tiles directly in front of a door or behind some often accessed equipment are great choices.
3. Release small mammals under the floor. Spread rumors about the computer room being haunted.
4. Remove a tile and stick your head under the floor. It feels nice and cool, and people will think you're an ostrich.
5. Throw confetti under the floor. Watch the ensuing hilarity.
6. Put hundreds of pro-revolution flyers under the floor. This tends to scare everyone.

Anyone have other ideas?
