Calvin and Hobbes by Bill Watterson for December 27, 1986
Calvin: Hey, Dad, I have a question. Dad: Sure, Calvin. What do you want to know? Calvin: If you plugged you nose and mouth right before you sneezed... ...Would the sneeze go out your ears, or would your head explode? Dad: I was kind or hoping you had a math problem or something. Calvin: ...Either way, I'm scared to try it.
