The Simpsons has seemingly retired the longtime character Duffman in a recent episode, marking the end of a 30-year presence on the show. Introduced in 1997, Duffman, known for his catchphrase "oh, yeah!" and voiced by Hank Azaria, was announced as retired by the Duff Corporation due to outdated advertising methods. While many interpret this as a permanent departure, some fans speculate it could be a meta-spoof, particularly given the episode's title, 'Seperance'.
