annoying co-worker is getting paid back, best $10 i ever spent.

"The ThinkGeek Annoy-a-tron would be useless against an army of Snowbots, but it's very effective at disturbing that guy in the sales department or your "friend" down the hall. With its thin design and embedded magnet for easy hiding, the Annoy-a-tron can be placed in a variety of locations. Select one of the three sound choices (2 kHz, 12 kHz, or alternating) and push the switch to the on position. Place it in a proper hiding spot and let the "fun" begin.

The Annoy-a-tron generates a short (but very annoying, hence the name) beep every few minutes. Your unsuspecting target will have a hard time 'timing' the location of the sound because the beeps will vary in intervals ranging from 2 to 8 minutes. The 2kHz sound is generically annoying enough, but if you really really want to aggravate somebody, select the 12 kHz sound. Trust us. The higher frequency and slight 'electronic noise' built into that soundbyte will make a full-grown Admin wonder where his packets are.

* 3 simple steps. Turn on.*
* Hide it.
