Hand Butler

Hand Butler! That funky Butler! Hand Butler, Jutler, that funky butler! Sorry about that, that's a take on an old beastie boys song called "Brass Monkey". Don't ask me what a "jutler" is, because I need a word to rhyme with butler.
I suppose that this next device needs no introduction. However, what you can't tell is that this hand bulter will send your snack (or any other device in hand) to a person just by pointing it in the right direction. The hand butler has a sensor that can somehow detect when it is reached the edge, so it will auto-stop.
You can get it at the What On Earth site, for about $20 USD, not including the 2 C batteries.
