I have the world's most expensive bottle opener - my Texas A&M class ring. 5 1/2 years and $thousands.
I was up on the 90-something floor of the World Trade Center in NY several years ago and they brought in Perrier - but no opener. "At the risk of looking like a Red Neck," I said, "pass 'em over." The folks in the room were stunned. Made the sale, too.
