Favorite letter "B"

Somewhere along the way Keenan has picked up the skill of identifying the letter "B", anytime he see's it he gets all excited, points and yells "B"! Of course at first Eric and I got all excited too; but that was like 500 b's ago. At the airport waiting for our flight to Krakow, Keenan was very busy pointing out all the B's he could find.
