Daily playing the voice of Tommy.
Sins of the Fathers Chapter 9: Tombstone - S3-E9
Trivia: When Spider-Man saves Tombstone from falling into a bubbling vat he jokes about him coming out with "green hair." Clearly that's a joke referencing DC comics' Joker.

Trivia: Peter Billingsley of "A Christmas Story" plays Gideon in this episode. This was his television debut at age 11.
Trivia: Nero, the pet "hairy caterpillar creature" of Baron Greenback speaks in a strange gibberish. In fact this 'gibberish' is a recording of David Jason (who also provided the voice of Dangermouse, amongst others) albeit it speeded up and played backwards.
Trivia: Robin Williams improvised so much of his dialogue that the show's writers finally stopped writing his lines and just left blank space in the scripts with cues and prompts for him.
Suggested correction: I'm researching Mork and Mindy for a feature. Contemporary interviews say Robin Williams was given leeway to improvise but this was only about 5% of an episode. These were probably done in rehearsals and incorporated into the final scripts. It would be impossible to film each episode if Williams wholly improvised as the cameras wouldn't know if he was going to hit his marks (i.e. where any actor needs to be so is in frame) and for other cast to react to. So partly true but not the whole story.

The Library - S2-E10
Trivia: Wan Shi Tong is of one the few things in this show that is not a reference to Asian cultures, but to Ancient Greece instead. In their mythology owls were the symbol of wisdom and their goddess of wisdom, Athena, was often depicted with an owl.
