Yes [1], mostly the episodes that involve Kaitlin Olson's character, Dee Reynolds, who aspires to a career in comedy, herself inventing and portraying racially insensitive characters within the story of the show.

I'm not the type to rail against such things generally, but IMO it was unnecessary and misguided to remove these episodes: their humor came deliberately from how oblivious Dee was to the offensiveness of her act.

Indeed, her portrayals are usually immediately and explicitly critiqued by her fellow characters as being racist and insane.

This is somehow the most mindnumbing. It's a show about terrible people doing terrible things. Like, they can only display certain, acceptable, forms of terribleness?

I think about 4 or 5 episodes.
