Tiny Toon Adventures

Tiny Toon Adventures is a cartoon series created by Tom Ruegger and executively produced by Steven Spielberg. It originally ran from September 1990 to May 1995. In 1993, it was spun off into Animaniacs, a show centering around three characters that the Tiny Toons encounter in one episode.

The series follows the many antics of a group of younger counterparts to the popular Looney Tunes characters, all students of the Acme Looniversity, set up by the original characters themselves to teach cartoon characters lessons on comedy.

That's Incredibly Stupid
Season 1, Episode 32 Airdate: November 6th, 1990

Plucky Duck and Dizzy Devil are contestants on a game show called "That's Incredibly Stupid". To win the grand prize, all Plucky has to do is judge a beauty contest. Curtains open to reveal the four finalist, all being skinny, attractive women. Plucky instantly starts drooling and accepts the challenge. Suddenly, the four women reveal they actually have huge muscles and the host reveals they are competing for the title of "Miss. Teenage Iron Pumping Kick-box Wrestler USA" and they will demonstrate their martial-arts skills with help from the judge (Plucky). Plucky is then tossed, tied, kicked, and thrown all around by the women. Plucky blindly picks a winner, the blonde, which makes the other three furious, and they take their aggression out on him (including the blonde). Plucky tries to pick a different winner to calm them down, but gives up.

 Trivia 

One can assume that Arnolda could be from Romania just as Arnold himself as no one had ever seen her before until she came to the prom.
