"you should have seen this before,
please pay attention"
When I published Invent! Magazine, we saw a lot of fad items come and go. Two of my favorites were the Wacky Wallwalker™, which survived several knock-offs because of its strongly trademarked name; the second was the guy with a boardwalk pizza shop that drew in business throwing pizza rounds, invented "fake" pizza dough to save waste, ended up winning contests with it, and got an offer from Domino's to package the units for Toys 'R' Us! It's a wacky world.
