S03E11 Adam's Ribs

Frustrated with the monotony of liver and fish for over a week, Hawkeye reaches his breaking point and instigates a rebellion in the mess tent. Together with Trapper, he decides to order the best spare ribs and sauce he ever tasted from Chicago. Trapper reaches out to a woman he had a weekend fling with to retrieve the ribs, which are soon delivered by helicopter. Just as they prepare to indulge in the feast, a group of wounded soldiers arrives, forcing Hawkeye to delay his long-awaited rib feast.
