Crocs. I got my first pair when I was a teenager and they still work now (edit: 30yrs old); though I recently got a new pair because the bottoms were completely smooth on the old pair.
"Ugly" cars. Aka Pontiac Aztec, PT Cruiser, Fiat Multipla, etc. Yeah, they might be ugly as sin, but they're more interesting from a visual standpoint. I'd rather have the road filled with ugly cars than filled with cars that mostly look the same.
