When the special aired at 11:30 p.m. on October 3, 1975, 22 minutes had been clipped from the original material. Gone was a cat used as a doorbell; a mention of “colonic irrigation” had also disappeared. ABC’s censors had snipped several “Good Lords,” “damns,” and other near-profanities. Any mentions of pooping were also trimmed. For Python fans, it was something akin to comedy castration.And that's where the story really begins.

The group didn’t learn the full extent of ABC’s meddling until late November, when they were shown a tape of the edited broadcast. Outraged, they demanded that ABC not re-air it.
The network had planned something worse: A second special was due in December, with the remaining three episodes due to be spliced in a similar manner.
With just days before that second program was scheduled to air, the Pythons filed a lawsuit seeking an injunction against ABC. They wanted their work removed from American broadcast television.
