Mr. Dreyfus: I probably shouldn't tell you this story, because it involves me being rebellious, but oh well. When I was taking physics, there was a problem involving a meterstick, and one of the students asked "how long is the meterstick?" To which the teacher responded "who is buried in Grant's tomb?"
And the student was puzzled. So I answered. But you know how I did it?
"Your mom."
