It's not at all uncommon for movies and TV shows to realise that a scene doesn't quite work during the editing process, and so promptly remove it before it ever reaches audiences.
Sometimes, of course, these deleted scenes are nevertheless made available to curious fans either online or as part of a home video release.

These 10 TV series all took the scissors to moments which caused them a major PR headache at one moment or another, gags and scenes that mostly didn't affect the episode's narrative, yet still left many decrying the slippery slope of self-censorship.
Though re-edited episodes aren't always a result of the network feeling pressure to remove an objectionable moment - as a single one of our examples proves - it is the most common motivator to crowbar open an episode that's already been delivered to the general public...
