Animaniacs Theme

It’s time for Animaniacs
And we’re zany to the max
So just sit back and relax
You’ll laugh ‘til you collapse
We’re Animaniacs!

Come join the Warner Brothers & the 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 Animaniacs! Dot is cute and Yakko yaks.
Wakko packs away the snacks
While Bill Clinton plays the sax.
(or We’ve got wisecracks by the stacks.)
(or We pay tons of income tax.)

We’re Animaniacs!
Meet Pinky and the Brain who want to rule the universe.
(or Meet Ralph & Dr Scratchansniff; say hi to Hello Nurse.)
Goodfeathers flock together;
Slappy whacks ‘em with her purse.
Buttons chases Mindy, while Rita sings a verse.
The writers flipped; we have no script
Why bother to rehearse?

Cast: We’re Animaniacs!
We have pay-or-play contracts.
We’re zany to the max.
There’s baloney in our slacks.
We’re Animanie, totally insaney

Cast: Animaniacs! Those are the facts![/size=2][/quote]
