Also, notice that this past year, with the obvious exception of New Year's Eve, not once did we see an episode from the first four seasons.
April 22 had "D.W. Thinks Big" / "Arthur Cleans Up".
Yes, I overlooked that, sorry, thank you.
But that brings to mind another interesting note... it almost seems as if when it comes to Season 1, "D.W. Thinks Big / Arthur Cleans Up" is just about the only episode from that season that gets any mileage anymore... I wonder why? It's not exactly the greatest episode there is (Corra alone is the reason for that), and with it being the longest season, why just that one?
