Can you run out?

The other day, Tyler and I were looking at old videos of him playing with a koosh ball. In the video he was making some cute and funny noises. Tyler thought the video was hilarious and laughed so hard! He kept asking me to play it over and over. After a few more viewings, Tyler didn't laugh as hard as before, and after a couple more times, he sort of just let out a loud, "Ha!" Then he looked at me and said, "Mommy, I'm running out of laughing."
