Another thing I started thinking last night for seasons 30 and 31: If they cut down on episodes because they just couldn't repeat street stories and squeeze in Elmo's World, I wonder how it would go over if they did episodes that were just insert segments, maybe with a couple of original street scenes just to open and close the episodes, maybe do those episodes once a week. I don't know if there was an average number of episodes each season that repeat street stories, but if they did the inserts-and-Elmo's-World-only episodes to fill 130 episodes, that would be about 65 episodes of just inserts and no street scenes.
Of course with season 30 being a big anniversary season, it would have been cool if they'd have half the season be more "repeats from past seasons", showing older street stories from the first 29 seasons, some of the more important scenes from the past, many of the earlier ones don't really have much plot focus so they could easily just leave out some street scenes (if the inserts between scenes weren't just shortened) and put in Elmo's World. And I'm thinking include old street stories from whenever and put in different inserts, as opposed to just shortening a full episode and attaching Elmo's World after that. I figure if they did they'd probably just include inserts that were still in circulation (so most likely no Roosevelt Franklin, Don Music, Baker films, Monsterpiece Theater with Alistair Cookie's pipe, Mad Painter, etc.).
Reminds me of an idea I thought up recently that would have been cool for season 30 (I know, too late), a commemorative collection of VHS tapes with each video spotlighting the best (and perhaps some rarities) from each season, like what Saturday Night Live has done, or maybe a collection of full episodes from the past (mainly best known, but maybe some less-celebrated ones as well). If a VHS collection were to spotlight each season, I wonder if they'd only include segments that were still allowed to be on the show (I would put in some street scenes from each season, those wouldn't have been on the show at the time).
