Machinist

This is one of those technologies -- photocopy machines, jumper cables -- that spark the question, What would happen if I used it on people? (If this question comes up often in your life, you might be Dick Cheney.) It's a device to measure your dog's body fat, handy if you fear your pug's turning into a pudge. Alas, looks like it's only available in Japan. No word on price, either. Still, try to get one; your dog will thank you.
