Brain and Pinky try to take over the world...with a new mouse, Larry. But can a third mouse really fit in with Pinky and Brain?
Larry Fine impersonator Billy West voiced Larry (using pretty much his Stimpy voice).
Three Stooges References
Larry is an obvious parody of Larry Fine,the middle man in the Three Stooges,which Larry also plays.
The Three Stooges theme song plays often in this episode.
In one scene,Brain gets wallpaper on his head,making him look like Moe Howard,a member of the Three Stooges. This is more obvious since each of them is supposed to represent a Three Stooge,Brain:Moe,Larry:Larry,and Pinky:Curly.
The idea of Brain,Pinky,and Larry posing as wallpaper hangers references that many cartoons featured The Three Stooges doing odd jobs.
A mouse parodying Zeppo, the middle man of the Marx Brothers,appears at the end of the cartoon.
