Forget Calvin. His dad was the man. Here's my favorite:
Calvin: Dad, will you explain the theory of relativity to me? I don't understand why time goes slower at great speed.
Dad: It's because you keep changing time zones. See if you fly to California, you gain three hours on a five-hour flight, right?
Dad: So if you go at the speed of light you gain more time, because it doesn't take as long to get there. Of course, the theory of relativity only works if you're going west.
Calvin: Gee, that's not what Mom said at all! She must be totally off her rocker.
Dad: Well, we men are better at abstract reasoning. Go tell her that.

LOL! Calvin & Hobbes was my favorite.
My four year old son had this to say this past Saturday about why the seasons change:
"When the time turns green, the temperature will melt.
When the temperature melts, the snow will melt.
When the snow melts, the time will be yellow.
And then it will be Spring!"
