A Little Worm in the Big Apple is an episode of the Alvin and the Chipmunks series.
Brittany, Jeanette, and Eleanor visit New York City to become stars on Broadway. They meet Uncle Harry on the way, who cons them by offering advice on how to get their roles in a week for a slight fee. Shortly after Brittany calls Alvin with the news, The Chipettes take part in an acting lesson, workout, photo shoot, and a singing lesson. Soon they get a note from Harry that says to enjoy their roles, which are actually a bag of onion rolls. With the help of The Chipmunks they are able to fool Harry into giving back The Chipettes' money, with a few additional personal affects, for a "piece of the pie."
