When i was a kid, we'd go to the football games at Memorial Stadium to watch an employee of the family business. Then after the game, I'd go around the stands and collect the green and white plastic cups. I'd bring home hundreds after every game. Just 3 weeks ago, we had a garage sale and my mother brought a bunch of them to sell. She didn't make any money on them.......they are sitting on the shelf ready for use as we speak.
