Other mistake: In the end when everyone is on the Kippie Kann show, they show the clip of Lulu and Joyce at the restaurant. It shows Lulu saying, "I'd say it's nice to see you, but then I'd be lying." In the restaurant scene, Lulu never says that.
Other mistake: In the scene where Barb gets the live show, Stacy says that Barb said an AP getting the live show was an urban legend. But if you go back to the scene where Stacy, Barb, and Ira are at the lunch table, Ira says that it was an urban legend.
