Back in the 70s there was a holiday gift sensation called the Pet Rock that came out one year. They sold millions of them. I got one for Christmas. It was one of those things that was so stupid it was kind of fun. And, just about as fast as they arrived, they faded away, as most fads do. Well, I noted the guy who invented them, Gary Dahl, has passed away. I suppose they're still around on places like eBay.
