In the early run of MG, I've seen a couple of answers being edited out entirely, only because the answer they gave was unacceptable to air. It doesn't affect the gameplay, but it is noticable when they skip a panelist that was supposed to play the question. Once, CNR gave an answer that was unacceptable for broadcast, but it was also an answer that matched. His answer was edited out and Brett, who was seated at the lower tier at the time, asked Gene what Charles had said. Gene mentioned that Charles said the correct answer, but no mention was made that it was unacceptable for broadcast. Unairable answers were a rarity for MG 7z, but in the later run, they'd simply put in an "oops" graphic over the panelist's answer.
Not surprisingly, the responses that referred to gay people pretty much stopped once CNR became a regular.
