This has to be the cutest video I've seen in a long time. Kids are so innocent when they are not brainwashed by their parents. I always say hate is tough and this is proof. I love how you can see him struggling with the concepts but then putting it together and being so excited and then as kids do.. he just wants to go play ping pong now.
I've watched this video over and over again and it makes me smile each time.
EDIT.. here's a story about the video and how it came to be: http://www.advocate.com/News/Daily_News/2010/03/10/Kids_Say_the_Darndest_Things/
