It feels like there's been a dry spell with adding classic season 1-10 episodes to Muppet Wiki. Not a complaint, just an observation. I remember a few months ago there were new additions nearly every week. But lately I haven't seen any new episodes that have been tabled, or with photos for the street scenes.
Side note: one of the more "recent" additions that has become a new favorite is episode 676, where Big Bird imagines he's living on Sesame Gulch in the Old West. Oscar also tries to conceal his feelings for Maria...great writing by Joe Bailey, with awesome inserts too. Heck, most of season 6 had some great episodes: 666, 680, 711, 725, 731, 733, 744, and 757 to name a few.
