Life is full of mysteries

How does a thermos know which things to keep cold and which to keep hot? Why does the tide go in and out? How does bread turn into toast? A dollar bill into a soda can? Food into poop? How can boats float if they're so heavy? If species evolve, why are there still monkeys?

What's the common theme here? All these are things Bill O'Reilly thinks we can't explain.

Enjoy.
