Kinda reminds ya of Hand (Addams Family fame ). As useless as it is, it's pretty darned cool.

This brings to mind another tool, but this one is very useful. It throws a ball for the dog, dog retrieves drops into machine to be thrown again.

Of course that brings to mind the beer fridge so that you can sit and watch all this action going on in style.

I think my lab would love the perpetual ball thrower, and I would love the beer thrower....

Oh yeah, our Lab needs the ball thrower! That guy's a genius!

I want a useless machine too! That's neat.

The automatic ball thrower is nice till you get the light bill.....
