The cardboard disc things that you stack up and hit with the plastic disc thingy then get to keep the ones that land face up... or was it face down? It's been a while.
Wow ... Pogs. I remember when they were a fad circa 1995: the store I worked at would have a plastic swimming pool on the sales floor filled with them. People would scoop them into produce bags and buy them by weight like CRAZY. Never understood that particular fad.
