Oh Brother Where Art Thou?

Trying to outrun the police, Ulysses Everett (with his friends and escaped chain-gangers Pete and Delmar) grabs the steering wheel of the bankrobber George Nelson's car ("grab the tiller will you buddy?"). This is because George wants to fire his machine gun at the pursuing police car. As he does so he yells "I'm George Nelson, no-one can touch me, I'm bigger than any Goddamn law that lives". As they pass a herd of cows in a nearby field George reflects: "cows... I hate cows worse than coppers" and starts taking potshots at the herd. Delmar, on the back seat, says regretfully: "Oh George, not the livestock"
