It's time for An-iman-iacs
And we're za-ny to the max
So just sit back and relax
You'll laugh 'til you collapse
We're an-i-man-iacs

Come join the warner brothers
And their warner sister dot
Just for fun we run around the Warner movie lot
They lock us in the tower
Whenever we get caught
But we break loose and then vamoose
and now you know the plot

We're an-iman-iacs
Dott is cute and Yakko yaks
Wakko packs away the snacks (this part changes with every season)
We're an-i-man-iacs


Meet Pinky and the Brain who want to rule the universe
The Feathers plot together, Slappy whacks them with her purse
Buttons chases Mindy while Rita sings a verse
The writers flipped we have no script why bother to rehearse

(in second season, when Pinky and the Brain had their own show, it changed to this:

Meet Ralph and Doctor Scratchnsniff
Say Hi to Hello Nurse
Good Feathers plot together, Slappy wacks 'em with her purse
Buttons chases Mindy; while Rita sings a verse
Our writers flipped; we have no script; why bother to rehearse)

We're animaniacs
We have pay or play contracts
We're zany to the max
There's baloney in our slacks
We're animany
Totally insaney
(changes like nearly every show)

An-i-mani-acs
Those are the facts
