 Arthur appeared as a guest in hand puppet form in a 1999 episode of  _"Mister Rogers Neighborhood" (1968)_ (qv), in which Mister Rogers  makes a visit to Marc Browns house and, later, Arthur makes a visit  to the Neighborhood of Make Believe. Mister Rogers himself appeared  (as an aardvark) in two episodes of Arthur. (One of these episodes,  Elwood City Turns 100, was aired after Rogers death.)
