Conserved Quantities

Panel 1: The mathematician (in front of the blackboard): You may have learned about conservation of mass or conservation of angular momentum. Today we're going to cover a new universal law of physics that's even more important than those. Panel 2: The mathematician (on the blackboard: (out of field vision)servation of sleep): I call it “conservation of sleep.” Panel 3: The mathematician: Conservation of sleep states that no matter when you go to bed or what time you set your alarm clock, you will always be 10 minutes late for class. Panel 4: Man: So, did you get a lot of work done over the 3-day weekend? The mathematician: zzzzzzzz…

It should have been a conservation of lateness. I need to be more precise about these things.
