The stereotypical impression of actor James Cagney involves wearing a trenchcoat and a hat and sneering "You dirty rat!", a line he never said. The origin of this is from the 1931 film Taxi! where Cagney delivered the line "Come out and take it, you dirty, yellow-bellied rat, or I'll give it to you through the door!" often misquoted as "Come out, you dirty rat, or I'll give it to you through the door!".
