Happy Smiley Face

One of the ritual Ryan does at school is singing a goodbye song at the end of the day. I don't know the song, except heard it from my wife, but it goes something like "... see you tomorrow with a happy smiley face." The kids sing that part of the song while putting their index fingers on their cheeks and swing their head to the left and right.
I know I'm biased but he's soooo cute when he does that :D
