Hartman is an outed and proven grifter, this type of thing is on brand for him.
Yeah, I'm not surprised by this in the slightest, given Harman has a history of running grifts, see Oaxis.
-sigh- Why does Nick seem to have an attraction to people who are either creeps (Bill Cosby, Dan Schneider, John K, Chris Savino), grifters (Butch Harman), or both? I'd think a network as big as they are, or at least *were* at one point, would have standards with who they hire.
