About this quote
Walter Sobchak (John Goodman) explodes at his bowling partner Smokey (Jimmie Dale Gilmore) in The Big Lebowski (1998), directed by Joel Coen. Smokey's foot crosses the foul line on a crucial roll, but Walter — a Vietnam veteran with an inflexible attachment to rules — pulls out a gun rather than let the infraction slide. The scene is one of the most beloved in the Coen Brothers' filmography.
