I am a sucker for totally useless facts. Did you know that a seashell has an IQ of 8? That means it isn’t smart enough to attract or hunt food—but it is smart enough to eat it if something happens to land on top of it. Or that with an IQ under 80, you can’t chew gum and walk at the same time.

Well, now you know. And a day when you learn something is never completely wasted.
