Back at the Barnyard S01 E48 Cowdyshack

Otis uses Crazy Louie – a loopy groundskeeper at a high-end golf course and apparently his friend – to let him and the animals through the back gate and play a round. When Pig throws a club and accidentally hits Louie in the appendix, though, a guilt-ridden Otis decides to win the big golf tournament to get a new appendix.
