One of the better cartoons on TV as well as a comic book about two lab mice, one a genius, the other insane, that attempt to gain world domination nightly, but fail due to any number of reasons, including stupidity, oversight, Brain's arch-nemesis, Snowball, or the rather attractive-and-distracting Billie. Produced by Warner Brothers Animation and is a spinoff of the Animaniacs cartoon, both produced by Steven Spielberg.
