A friend of mine started selling these..

I bought a few and put it in peoples offices. It is freaken hillareous.
As a payback to a friend who always used to move my trash can at work, i put it under his keyboard drawer doublesided sticky tape set it to 5 minute soft chirp. Its ben 3 weeks he hasn't found it yet. We know it anoys him because every now and then we see him turn down his music and start listening for it, but gives up after a minute or two and goes back to his music, then it beeps again!
i'm gona buy few more and maybe throw one in his truck!!!
Any other ideas?
payback to your co-workers/wife/ etc etc?
