I'd actually like to see more of those stop motion versions of older animated skits and songs, but similar to the "Pinball Number Count" competition, something that uses the original recordings. Haven't seen that European (?) studio's animation for some time in the series. The same ones that did the Ernie and Bert stop motion series.
But it would be a great way to reintroduce older songs and pad the number skits they desperately need so we don't have so many "look at the number hidden in the rocks" type skits that are...just there.
Of course, considering how the number of the day segments have all but been banished from the show, I'd hope they'd actually have run time for something like that.
