This reminds me of a story one of the math professors at the university I attended told once. He said he was standing in a class teaching the Math for Elementary Educators class, when someone asked him why they needed to know 8th grade mathematics. Apparently the elementary school teachers in my state are qualified to teach up to 8th grade, and so he needed to make sure they actually knew 8th grade math.
