This is a reference to the most famous line from the 1942 biopic Yankee Doodle Dandy starring James Cagney as songwriter George M. Cohan ("You're a Grand Old Flag" et al.). The recurring line in the film is, "My mother thanks you, my father thanks you, my sister thanks you, and I thank you." This line was honored as number 97 on AFI's 100 Years...100 Movie Quotes list.
