Mario says "Fuck you!" to Luigi on "The Super Mario Bros. Super Show!" (1989)

My 13-year-old son showed me this and we couldn't stop laughing. How dare Mario be so rude to his brother!

The 1989 TV series "The Super Mario Bros. Super Show!" starred wrestler Lou Albano as Mario, Danny Wells of "The Jeffersons" as Luigi, and Jeannie Elias as the voice of Princess Toadstool.
