Looking at the page for 1936, I learned of an alteration to an old sketch that I was not aware of (but am not surprised they did). It has the Kermit and Grover "toothbrush salesman" sketch, but cuts the ending, I assume the whole part where Kermit bites Grover (surely that's not a post-roll that we happened to previously get an episode with). It seems that one hasn't been broadcast since the 1980s, I figured the ending was too much, but if they did just cut it, I wonder why they discontinued (the edit bad? did they think Kermit's teeth here looked too creepy? - and admittedly, his teeth do look a little creepy compared to his teeth in the health minutes sketch). Assuming it was pulled and not a case of them just not getting around to airing it in the 1990s.
The street scenes look decent as well, with Slimey doing a rhyming trick and Don Music singing a song that just rhymes the word "school".
