41 years in, Saturday Night Live has its routine down pat, including a reel of promos aired midweek leading up to each Saturday's episode. Yesterday, a video was uploaded to SNL's YouTube channel which included 8 clips, a little more than usual, because it was the wrong file and included ones that were supposed to be cut. It was NBC's biggest "oopsie" since inviting Trump to host SNL after cutting ties with Miss Universe over his racist comments, if it was even an "oopsie" at all.
