Santa Claus = Coming

Rachel saw Santa on "Miracle on 34th. Street" a few weeks ago and pointed to the screen and said "Who dat?" We told her and when he'd go off the screen she'd call out to him. Since then, she'd make sure we saw Santa wherever she saw him. Until the last few days. Now, if she sees Santa she says "coming!" We wonder if they're singing "Santa Claus is coming to town" at school?
