The only possible comparison would be if some show had a gimmicky live episode that happened to be scheduled for 9 AM, on a Tuesday, in September of 2001.
Speaking of, not the child focused Sesame Street, but they accidentally made it canon that in the Muppets universe whether or not Kermit the Frog exists somehow determines whether or not 9/11 happens. 2002’s “A Very Muppet Christmas” is an “It’s a Wonderful Life” style movie where Kermit temporarily wishes himself out of existence and is allowed to observe the resulting timeline. Shots of the Manhattan skyline in the main universe show no Twin Towers as expected, but there’s a shot that clearly shows them in the background outside alternate Piggy’s window. Accidental because the set designer or whoever just didn’t notice them in the old still used for that window, but the implication is hilarious
