Glad he weathered the ordeal well. It's always nerve wracking when they have to get knocked out for something. And, yes, that loopy, crazy-eye expression never fails to make me giggle. It's okay if you laughed, too. I can almost guarantee he won't remember you did it.
Oh, and the pearlies look awesome!
He's back to his old self after his nap. I'm still chuckling as I look at that picture in the car. His expression is too much!
They bounce back pretty fast. Good thing you took the pics when you did. Those are the ones you'll remember for years to come - and they will STILL make you chuckle. Make sure you save them in a safe place.
