• I ordered a club sandwich, but I'm not even a member. "I like my sandwiches with three pieces of bread." "Well, so do I!" "Then let's form a club." "OK, but we need some more stipulations. Instead of cutting the sandwich once, let's cut it again. Yes, four triangles, arranged in a circle, and in the middle we will dump chips." "How do you feel about frilly toothpicks?" "I'm for 'em!" "Well, this club is formed."
