Annoy, Annoy, Annoy
If online pranking isn’t your thing, you can always turn to ThinkGeek, and their glorious mail-order devices. The Annoy-a-tron can be hidden anywhere. It makes annoying noises – six different kinds! – and the battery lasts a whole month. So you can keep the fun going long after April 1 is a distant memory. Just magnet that thing in and wait for the chirping to begin. It’s like a smoke detector that just won’t quit.
