The Law of Lincoln

Some of you have been able to witness this first-hand, but for those who have not, here's a picture of how Lincoln likes to sleep.

It never fails, if we take the blanket off of his face, he rarely wakes up. But if we check on him after an hour or two, the blanket is back over his face. It is observable and repeatable, we've followed the scientific method, and it has just about become the Law of Lincoln.
