If you don't like the Animaniacs, then you are a communist.Only on air for 5 seasons, this half hour of zany antics gave birth to other cartoons like Freakazoid and Pinky And The Brain. According to IMDB:

Ensemble cast of off-the-wall Warner Brothers characters, appearing in a wide variety of roles. Wakko, Yakko, and Dot Warner, are WB Studio creations who were just too "zany" to be of any use to the studio.

This particular bit was one of my all time favorites, and the second I found it on YouTube, I new I had to share with the class.
