GREAT question!

So tonight at bedtime, Monkeyman & I were doing this thing we do, where we jokingly compete for who loves who more:

Monkey:  I love you!
Me:  I love you 7 times more than that!
Monkey: I love you 10 times more than that!
Me:  Well, I love you 35 times more than that!
Monkey:  Well, I love you 100 times more than that!
Me:  Oh yeah, well, I love you 1,000 times more than that!
Monkey: I love you 100,000 times more than that!
Me:  Well, I love you a million times more than that!
Monkey:  (pauses) Hey, what is the last number?

"Last number" meaning:  "What is the very highest number?" so he can use that to outdo me.  It just struck me as a really great question - I love the way his mind works.  I told him that there is no "last number" and explained the concept of infinity and he thought that was really cool.  "Oh, like on Toy Story, right?"  And I replied that yes, when Buzz Lightyear says "To Infinity and Beyond" he means "On and on, forever."

So that's our math lesson for the day - a review of the concepts of "greater than" and "infinity".  :)
