Who's The Leader Of The Club That's Made For You And Me?

This is from last night. Again, no coaching or suggestions or anything said by me or Jenn. He was kind of singing the song as he started putting the letters together. We're slightly torn...my god, he can spell, already! I mean, he's spelled "house" now, based on how to spell mouse. He know "mom," "dad," and also "car." But on the other hand, could such a big phrase like Mickey Mouse, be done if he hadn't seen "Mickey Mouse Clubhouse" so many times?
