Sesame Street episodes with recycled plots

Since it was hard to produce 130 shows a season, sometimes an episode's street scenes from two seasons ago were recycled and mixed in with a different set of inserts, to create a new episode. This list is of all the known episodes which contain the same street plots. This practice started as early as Season 6 and lasted until Season 33, since there were fewer and fewer shows produced each season from then on.

NOTE: Due to the introduction of Elmo's World, no episodes in Season 30 and Season 31 had any recycled plots from Season 28 and Season 29.
