Unusually for a season 2 episode, all six regulars - Mork, Mindy, Remo, Jeanie, Nelson, and Mr. Bickley - appear together in one scene.
Mindy leads the children in "I won't grow up," a musical number from the 1954 stage version of Peter Pan. Robin Williams later played a version of Peter Pan in Hook (1991).
"Looney Tunes" and "Merrie Melodies" were the two branches of a franchise of animated comedy shorts produced by Warner Brothers from 1930 to 1969. Iconic characters introduced in the series included Bugs Bunny, Daffy Duck, and Porky Pig.
