I wouldn't put it past them to get that to work, though. I'm sure they could just pick the show apart to add some Muppet moments back into the show. Even wholesale unaltered versions of that segment would be a lot less dull than the same Abby segments over and over... but you have a point. That would be a terrible flow, since the show's been broken up to something like that essentially already. Maybe if they break the segment apart or something inside the show?
But that does pose the problem for Abby. On the one hand, that's 9 minutes of the show the show gets back, but considering they're scrambling to fill up the episodes half the time already, it's a question of what could fill in that slot. If they already have to use footage from the same season twice before the halfway mark, that means they are kinda desperate for filler segments.
