Summary: Imagine this: It’s your first day of art class. You signed up for an intro class on pottery. (Nice! Go you!) The teacher does something a little weird. He points to one half of the class and says, “On the last day of class I’m going to bring in a bathroom scale. You guys will get an ‘A’ if you produce 50 pounds of pots. A ‘B’ for 40 pounds. 30 pounds gets you a ‘C.’”
