In the Spongebob season 2 episode Shanghaied, during the original airing viewers could call in and vote on the ending of the episode out of who got a wish; spongebob, patrick, or squidward. Patrick and Squidward lost the voting and their endings were played first after a short clip of Patchy saying they lost. Afterwards spongebob's ending was played, once more after a clip of Patchy the Pirate, this time saying the winner. These would have been pre-recorded and aired according to the voting results, so could a clip of patchy saying Spongebob lost the voting theoretically exist? How about a clip of Patchy saying Squidward or Patrick won?
The alternate endings exist but I'm speaking about the short clips of Patchy before-hand. There are 3 separate clips of him when, if every result was accounted for, there would be 6 created but 3 would never be aired.
I think the youtuber PieGuyRulz said in his review of season two that he has a DVD, or is aware of, that has the original unedited episode of Shanghaied.
Apparently, these do exist. Someone has linked me to clips of Patrick being the winner, and Squidward being the winner. However, the clips are in Spanish.
