Calvin and Hobbes by Bill Watterson for June 17, 1995
Calvin: Why does ice float? Dad (Calvin's father): Because it's cold. Ice wants to get warm, so it goes to the top of liquids in order to be nearer to the sun. Calvin: Is that true? Dad (Calvin's father): Look it up and find out. Calvin: I should just look stuff up in the first place. Dad (Calvin's father): You can learn a lot, talking to me.
