Appearance: "I Am Furious Yellow," Season 13. After Kirk van Houten gave a particularly depressing assembly presentation on his career (as the assistant to the guy who puts fliers under windshield wipers) Principal Skinner, Mrs. Krabappel, and Lisa tried to find a different speaker for their next assembly. Sadly, that was not another debate between proud-Scot Groundskeeper Willy and one of his many, many enemies, Irishman Groundskeeper Seamus, who was apparently fired after being relieved of his debating-duties. Funniest Moment: This is also his only brief moment, but- after hearing of his dismissal- Seamus automatically blamed Willy. Seamus: "This is your doin', Willy! I'll turn your groin to puddin'!" Willy: "Ach! Ya speak like a poet, but ya punch like one too!"
