Bert and Ernie (or Da and Baba)

Andy and Michael like to tease each other. Well, mostly Andy likes to tease Michael. On Elias's alphabet placemat, Andy told Elias to point at Ernie and say, "Michael." So now everytime Elias sees that picture, Elias says, "Da." (That's how Elias says Michael.)

To get Andy back, Michael told Elias to call Bert, "Baba," which he does. So, when Elias sees the picture of Ernie and Bert, he will giggle, point, and say, "Da. Baba."
