* At the end of "The Fight of the Felix", when Oscar takes a punch for Felix and they have their "standing up for each other" talk.
* A meta moment; when Jack Klugman was hospitalized for throat surgery, the first person to come to his side was his dear friend Tony Randall.
* The ending of "The Fat Farm" where Oscar tells Felix that he'll be happy even if he only lives 20 more years while Felix lives 25. Felix's (tearful) response? "I'll miss you."
* PaulWilliams ParentalLoveSong from "The Paul Williams Show."
