I never knew the "Arthur and Annie look for A" was classified as a "Filmfair" segment. I know, according to Muppet Wiki, there was a Filmfair Q segment, and even a Filmfair G segment. Since there are no Filmfair segments for G and Q available on YouTube or anywhere, it has been hard to know what they are like, until I just found out now about the "Filmfair A" segment. I have to admit, the "Filmfair" segments were likely only shown on Sesame Street until around 1981, maybe even 1982, but I don't recall on Muppet wiki any occurrence of "Filmfair Q" on any episode guide for Season 13 (1981-82), but from what I remember, they likely didn't last long in the 1980s.
I do know there are some animated inserts that creeped me out, such as "Y for Yawn", "Goldilocks Takes a Bath", "The Bee Bee and Barker Family" and "Now Then... a Count of Ten" (listed on Muppet Wiki episode guides as "Scanimate Films #10"). I still do feel sensitive about the Y and 10 segments (possibly due to my autism), but the Goldilocks segment would turn me away because of her brief nudity, which would turn me away then, and I would still be turned away from the segment if I would have continued watching the show to this day (even if the segment would be on YouTube). And the Bee Bee and Barker family segment turns me away because of my then-hatred for bare feet (though I would have no issues with bare feet in modern media and modern celebrities these days, if wearing sandals).
Ironically, I seemed to have no problem with the letter B segment about a certain boy and Bosco taking a bath and producing bubbles, despite that the boy was briefly nude. This means I am turned away from nude females in any media, and consider me more of a TV-PG kind of person, at most. I can handle some TV-14 stuff, but not nudity. And after seeing said segment, I discovered that the way the letters were drawn, and the style of the African-American boy used in the segment, it makes me wonder if it was by the same artist involved in the number 6 segment, "I'm six years old today"?
