Saturday Morning Breakfast Cereal by Zach Weinersmith for November 24, 2014
I wish there were puppies all over the place! Don't you see? With science there are! Dogs are mostly made of oxygen, nitrogen, carbon, and hydrogen. Guess what? Air is made of the same stuff! Because atoms are physically indistinct, there's no difference between a dog carbon atom and an air carbon atom! So dogs are everywhere! Above you, behind you, in the day, in the night, in the closet, on the ceiling, under the bed. Why... So to speak, every time you eat, you're eating a puppy! Every time you breathe, you're inhaling a puppy. That's horrifying. Hey don't thank me, thanks science. I didn't thank you. Sound waves are also interchangeable!
And they get recycled. It’s said that there’s high probability that even now you are breathing the same oxygen atoms as Julius Caesar once did.
