who said you dirty rat in a movie
James Cagney Taxi! was the source of one of Cagney's most misquoted lines; he never actually said, "MMMmmm, you dirty rat!", a line commonly used by impressionists. The closest he got to it in the film was, "Come out and take it, you dirty, yellow-bellied rat, or I'll give it to you through the door!" The film was swiftly followed by The Crowd Roars and Winner Take All.
