James Holzhauer has certainly been unafraid to comment on all things Jeopardy!, even as the show spirals through a series of controversies over picking Mike Richards to host the show. But one joke he made about another guest host, Joe Buck, earned a response from the sports broadcaster.

Buck closed out Season 37 of Jeopardy! with a hosting stint, and while the ratings for his showing aren’t in just yet, it’s safe to say that Holzhauer — a professional sports gambler who has assuredly heard a game of 500 that the veteran broadcaster has called — wasn’t exactly a fan of Buck in general. He tweeted two jokes about Buck on Twitter that essentially said he wanted Buck to stop broadcasting football games.
