Stuck in a boring job? Fed up with dreary days filing TPS Reports and trying to avoid responsibility? Wish you could do something to contribute to the welfare of your fellow workers while at the same time earning credibility points from the Ashton Kutcher school of pranksters? Well we’ve got the perfect thing for you.

The Ringtone Annoy-a-tron is a small gadget which comes with a set of magnets (for attaching under chairs, filing cabinets and other metallic office furniture), a battery which will last for 4 weeks of use and a volume control. What does it do?

It plays your selected ringtone at a set volume at random times during the day (and night) for as long as the battery lasts. Hunt the hidden cell phone, geddit? If you make the volume low enough and the ringtone annoying enough, you can probably expect to send your boss nuts in around…ooh…2 weeks. Can you spell the word diabolical? Priced at $11.99, but comes with no bodily injury insurance, so be careful.
