S13E12: The Lastest Gun in the West

In the episode "Simpsonlar - S13E12: Episode 12," also known as "The Lastest Gun in the West," Bart befriends an old cowboy movie star named Buck McCoy. Bart is impressed by Buck's tales of the Wild West and his impressive skills, but soon discovers that Buck's glory days are long behind him, and he's now a washed-up alcoholic. Homer and Bart try to help Buck get back on his feet by arranging for him to appear on the Krusty the Clown Show. Buck initially does well, impressing everyone with his cowboy skills, but his old habits catch up with him, and he ends up getting drunk before his big performance. Despite this setback, Buck manages to redeem himself when he heroically saves Springfield from a rampaging bull that had escaped during the show. With the bull subdued, Buck regains some of his lost respect and decides to stay sober, showing that even an old cowboy can learn new tricks—or at least rediscover some old ones.
