Query: What a clever way to teach!!

I have a 4 year old son that watched his father play other games and begs to play too. Those are too old for him and way to difficult. We purchased this game in hopes that he could learn and stay entertained.... Well, two days after his limit of 1 hour of play daily, we went to the post office and he told me all the letters that were on a sign. I asked him how he knew that and he simply stated "Elmo taught me, Mom!" Way to go Elmo!!
