Calvin and Hobbes by Bill Watterson for April 23, 1993
Calvin: Curiosity is the essence of the scientific mind. For example, you know how milk comes out your nose if you laugh while drinking? Well, I'm going to see what happens when I inhale milk into my nose and laugh! Susie: Idiocy is the essence of the male mind. Calvin: I'm guessing it will shoot out my ears. Don't you want to see??
