Factual error: When Morty is showing Michael how to use the remote, Michael rewinds to a family vacation in 1976. A childhood friend of his invites everyone over to his parents' RV to watch Three's Company. Three's Company didn't premiere until 1977.
Suggested correction: Although technically this is true, ironically there WERE two pilots for Three's Company filmed in 1976 with some similar and some different cast members, which may or may not of actually aired at the time after being filmed. The 3rd and final pilot with the familiar cast got the show finally rolling in 1977. So the mistake stands, but it could be a bit iffy based on this info.
This mistake does not need correction. This is just trivia that does not impact the mistake. Both pilots were unaired, so they couldn't have watched it on TV. Additionally, this was his summer vacation and the first pilot was taped in May and the second one was taped in November.
