that was like a waffle maker for burgers.. you put the meat in, close the lid, and it fried both sides at the same time.. made a pretty good burger!
but the best "unknown" invention I ever bought - and still have -was the charcoal-less BBQ grill.. it was just a large metal pail, really, that you wadded up sheets of newspaper into balls and threw about ten of those in the pail and lit it.. Seriously - that thing cooked a burger PERFECTLY in less than two minutes.. I can't believe they went out of business.. that was a BOSS invention...
Friendship is like peeing your pants.. Everybody can see it, but only you can feel the warmth..
