Having completed their quest and busted all known myths (including those based on Indiana Jones, Breaking Bad, and The Simpsons), Adam Savage and Jamie Hyneman from MythBusters will be hanging up the walrus mustache and crash test dummy for good after the show’s next season. That comes from Entertainment Weekly, which notes that ending next year will make MythBusters the longest-running show in Discovery Channel history, with 14 seasons, 248 episodes, and 2,950 experiments conducted. Also, Savage and Hyneman have known for a while that the end is coming, so they’ve specifically made sure that the final episodes will be a worthy sendoff for the series—with Hyneman noting that “there’s an emphasis on looking back.”
