Kids make me laugh

I'm on the phone:

Me: yeah, I'm really excited. Just got a book on training for Ironman.

Nicholas looks up from doing homework, bright-eyed and excited: Mommy, you're going to train to be Ironman? Can I be Ironman, too?

Me: Hold on... No, Nicholas, not Tony Stark, a long long hard triathlon race called Ironman. (I show him the book).

Nicholas, grumbles and goes back to homework: Oh man! That would have been so cool.
