Suite Life of Zack and Cody, The Easter Egg - I Like My Old Character Better

In the episode where London (Brenda Song) meets Mr. Moseby's niece, Nia, she gets her name wrong on several occassions. At one point, she calls her "Tia." When Nia corrects her, London replies, "I like Tia better." No wonder-- Tia was the name of Brenda Song's character on "Phil of the Future!"
