  • 5 settings to mimic frequently-heard ringtones

The Annoy-a-tron pranking device has been one of the most popular ThinkGeek products almost as long as we've been on the internet. We get emails all the time about roommates driven insane, co-workers emailing IT with documentation about the beeping, and friends concerned about supernatural activity in their apartments. Mwah ha ha! We love the evil.

And we thought... how can we be MORE EVIL?

Enter the Ringtone Annoy-a-tron. Like our standard Annoy-a-tron, this small device can be hidden anywhere: in a drop ceiling, under a desk, behind a cubicle wall, under a chair. The attached magnets make this even easier! Select your ringtone from a selection of five familiar sounds. Then stand back and try to keep a straight face as the people around you search desperately for the phone that's ringing at random intervals throughout the day. One battery will last you up to 4 weeks... or until someone finds the device and smashes it with their Hulk-rage. Hide it well, friends!

Please Note: As you can see from the video below and the image above, we've upgraded the Ringtone Annoy-a-tron into a new (and circular) form factor. It's smaller, but better!
