Animaniacs

Animaniacs is a cartoon series created by Tom Ruegger and executive produced by Steven Spielberg for Warner Bros. Animation that aired from September 1993 to November 1998 and has achieved cult success for many years afterward.

It consists of cartoon segments focusing on various characters in each episode, mainly the adventures of Yakko, Wakko, and Dot; three cartoon siblings who were locked inside the Warner Bros. water tower for six decades in the 1930s. One of its segments, Pinky and the Brain, was successful enough to earn its own spin-off series.

The show's long-lived popularity eventually prompted a revival series taking place in the modern-day, which began streaming on Hulu in November 2020.

In a parody of American Gladiators, the Hip Hippos appear in the game show "Amazing Gladiators". They face off against the game's reigning champions, a very athletic couple named the "Punishing Petersons", on the cusp of their 1000th consecutive win.

While Mr. Peterson has a hard time defeating Flavio's bloated body, Mrs. Peterson beats Marita in both putting on tight jeans (although she struggles to get the pants past her toned butt) and shooting bowling balls with a bazooka. Both of these victories are short lived however, has they both also result in some kind of physical damage, again due to the Hippos' large bodies.

In the final event, the Petersons are able to eat their way through a pool of food and claim victory, although their once fit figures are now just as fat as the hippos.
