Dewey Fishbeck is the Anchorman on KTNS TV's nightly news, where Mindy works. He is also, alongside Orson, the 'other' repeatedly referred to character who we never see onscreen. Though unlike Orson we never hear him either.
About Dewey Fishbeck[]
Dewey is probably the singular reason why Mindy is expected to appear on camera as part of the terms of her employment at KTNS. From Day One he doesn't show up for work, leaving her to carry the can. And while a blizzard may be a legitimate excuse it becomes apparent over time that Dewey is not very adept at his job. Mindy is the one sent out to try and interview Robin Williams when he is town, so that Dewey can read out the interview on the air.
Dewey's on screen presence is also not much of a draw, as according to station manager Miles Sternhagen, Dewey Fishbeck's Farming Report is literally bottom of the local ratings.
She also writes the questions for him to ask the State Governor, telling Mork that the only thing Dewey's good at is making jokes about the sportscasters jacket. Ultimately she ends up having to travel to do the interview herself as Dewey has an allergic reaction to his own toupee and has broken out in hives. He also dumps work on her on her day off by refusing to follow up on the story of the used car salesman whose been kidnapped (who no one will pay the ransom for), ruining Mork & Mindy's romantic plans.
