I'm not a fan of shower games but this one I went to in the late 70's literally took the cake. Each person was given a toothpick, a small piece of cardboard and a stick of gum. You had to chew the gum, spit and/or place it on the cardboard and with the toothpick, try to sculpt something of it. Everyone's "sculpture" was then placed on a table and judged. Whoever won got a prize. No I can't remember just what the prize was but it was probably in keeping with the game itself. No one I've ever described this to has ever heard of such a thing and I swear, I couldn't make this up even if I wanted to. Maybe it was some sort of bizarre, central New York kind of thing.
