At the first stop, we were handed a small envelop. Inside were six different drill bits. We were confused, we speculated that one was 7/8, and one was 3/32 and so on, and maybe you should combine the numbers in some way. Or maybe one of a series was missing and we should know that. Suddenly, I shrieked, "Don’t you get it, six bits!" Here you had to know that two bits is a quarter, and so on. There’s a football cheer that goes, "Two bits, four bits, six bits, a dollar. All for the Jackets, stand up and holler!"
