Wednesday Will-isms: Infinity

We have this crazy kids CD by They Might Be Giants. The songs are really creative, but a little on the weird side, and they're all about numbers. Will's new favorite is a song about infinity. Now, whoever thought it was a good idea to put a song about infinity on a kids CD needs to come to my house where they will be promptly buried in questions:

Will: "Are there more sidewalk squares than infinity?"
Me: "No, Will...infinity is the biggest number ever. Nothing is bigger than infinity."
Will: "Is that branch bigger than infinity? What about that tree? (Continues for a really long time asking whether different items are bigger than infinity. I attempt to be patient and continue to tell him that no, our house is not bigger than infinity.)
Will: "All the way up to heaven is bigger than infinity."
Me: "Well, okay. 'All the way up to heaven' might be the definition of infinity."
Will: "So, how can I get to infinity? Can you use a ladder? A rope?"

I guess I can't really blame him that he hasn't mastered this philosophical concept yet. After all, he's only three. But when he turns four, I'm not cutting him any more slack.
