You have to love Concept Shed's AutoWed, instant matrimony. Put in your dollar, and it talks you through the ceremony after you input names, music included. The robopreacher gives you a certificate/receipt and a couple of rings that look like they should have come out of a Cracker Jack box. We're not sure how legal it is, but it has at least as much charm as an Elvis impersonator. If you happen to live close to Detroit, you can see one at Marvin's Marvellous Mechanical Museum.
