The device is thin, so it can be taped to the bottom of a drawer of desk. It will generate a beep every few minutes, which at first gets themcurious. It lasts 2-4 days. Now, I don't recommend keeping it there for THAT long though.

I need one of these for my professor jerk butt

Ha - love it!

I bought one of these...works great for that person in the cube over that turns the radio up just a little too loud.

I'M SURE YOU HAVE THAT PERSON IN YOUR LIFE THAT IS AS ANNOYING AS A SMOKE DETECTOR WITH A DYING BATTERY I KNOW I DO! WELL NOW THE FEELING WILL BE MUTUAL! THE ANNOY-A-TRON IS SLIGHTLY LARGER THAN AN AMERICAN QUARTER AND EMITS A TINY BUT CLEAR BEEPING NOISE EVERY FEW MOMENTS! HIDE IT IN AN IMPOSSIBLE PLACE TO REACH AND KEEP A STRAIGHT FACE WHILE YOUR BUDDY GOES BERSERK TEARING APART THE ROOM!

I've always been a good girl- mostly because I'm too afraid I'll get caught- but this little gadget could enable me to realize my most evil vengeful impulses. With it's magnet for easy hiding I can now drive my nemesis crazy with horrible beeping noises that go off at random intervals- with little chance of getting caught. MWAHAHAHAHAHAAHAH.

Do you know where that annoying random beep is coming from? They don't. One word: April Fool's Day. (via thinkgeek.com)

I've always liked cool gadgets, expecially cool gadgets that I can use for "evil" causes, also known as having a laugh at sombody elses expense. I'ld love to hide this in a classroom at school, that'ld be amazing because of some of the stupid people in some of my classes.
