Annoy-a-tron drives people mad

Ever had an irritating colleague whom you just can’t seem to get rid off? It is about time you got your own back with the Annoy-a-tron from ThinkGeek. This devilishly devious device comes in a thin and extremely small design that makes it easy to hide without being discovered. There are three sound choices to choose from to annoy your target to death – 2 kHz, 12 kHz, or alternating. All you need to do is to plant it somewhere and turn it on. It will generate an extremely short beep at random intervals of 2 to 8 minutes, guaranteed to send anyone sane into a straightjacket with time. Half the fun is seeing your victim trying to look for this device, while the other half consists of seeing the priceless look on his face trying to figure out what exactly the Annoy-a-tron is. A single battery is enough to annoy someone for 3 to 4 weeks. Each Annoy-a-tron retails for $9.99.
