On TV: a "Flintstones" episode where Fred dresses as the superhero "Superstone."

Interesting how superheroes were parodied before "Batman '66." "Superheroes" = "Superman", specifically the 50s Superman TV show. (The actor Fred replaces is even named "George"---a George Reeves reference?)

Also the villains in older superhero parodies seem to usually be mobsters/crooks (rarely an actual mad scientist). Never parodies of Lex Luthor or the Joker?
