In college a friend had about 10 of us dumbfounded for an hour as we tried to figure out what "The land of Nodd" was. The land of Nodd has floors, but no ceiling. It has grass but no lawn. It has no animals but there are teeth. Etc. The game is we asked him questions about whether it has something or does not, and we had to figure out what "The land of Nodd" was :P
