I still wonder how can a concept as funny as Pet rocks could create so much wave in the 70s. People then, actually bought the Gary Dahl’s idea of taking pebbles as the best substitute to keeping real pets. Though the fad didn’t last much, it did manage to become a toy craze for some time. Now ThinkGeek is trying to revive the idea and hopes that it might also work. They’ve come up with a USB Pet Rock, but that doesn’t do anything just like the 70’s Pet Rock. It literally won’t do anything, and all you can do with it is plug it into a USB port and forget.
