Bart: If TV has taught me anything, it's that miracles always happen to poor kids at Christmas. It happened to Tiny Tim, it happened to Charlie Brown, it happened to the Smurfs, and it's going to happen to us!
Bart references two animated Christmas specials. The 1965 classic A Charlie Brown Christmas; and the 1982 yuletide special The Smurfs Christmas Special. (Also used as a parody in the form of The Happy Little Elves). Plus a reference to Charles Dickens' A Christmas Carol.
