The ‘Really Bad’ Worf Line Michael Dorn Roasted When He Didn’t Know Ronald D. Moore Was Standing Behind Him On The Star Trek: The Next Generation Set | Cinemablend

That first season on Trek, 'Sins of the Father' was the episode. It was a Worf story. Worf goes back to his homeworld for the first time and has this whole thing about his honor. I was down on the set and I'm digging it: 'It was a big Klingon show, this is kind of cool.' There's Michael Dorn and he has this line in a scene where he discovers one of the other Klingons has betrayed them. The line is, 'Someone should feed this Ha'dibah to the dogs!'... and Michael immediately goes, 'You know what? It's a great script but then somebody writes you a line of dialogue like that and the whole thing is just so stupid.'

Michael Dorn obviously wasn't a fan of the line, but he's stated many times over the years he is a big lover of Worf. Fortunately, he remained (mostly) professional during the filming of the episode. Ronald D. Moore didn't even scare him away from playing a Klingon, even if the line was terrible.

There's more to it but that's the gist. The writer continued to write and shined despite this one off "gaff".
