There is no quibbling:
The sweetest relationship is sibling to sibling.
My emotions have left me... dribbling.
I´ll stab anyone who starts gnawing and nibbling
At my feelings for my sibling!

We've danced it in the graveyards
Where the maggots bill and coo
It's perfect for beheadings
Where the head says "How-dee-do?"

Mamushka! Mamushka! I doff my old babushka!
With a hey and a hey and a hey and a hey and a dance of brotherly love!

Just kill the Carioca, continental Susie Q!
Garrotte the old Gavotte and disembowel the Dipsy Doo!
Mamushka! Mamushka! Let´s dance it like [bad word] 
With a hey and a hey and a hey and a hey and a dance of brotherly love!

Brothers! Brothers! BROTHERS!

The Brothers Karamazov, and the German Brothers Grimm,
There's Orville Wright - and Wilbur! - Orville's nothing minus him!
The Smith Brothers, and the Marx Brothers and the Ritz and the Brooks and
the Everly Brothers,
Solomon Brothers, Nicholas Brothers, Corsican Brothers...
And Doctor Joyce Brothers! Brothers!
Ringling Brothers - watch them break their back!
The Warner Brothers, Harry, Sammy, Irving, and Jack!

I know there´s a host of others
I've had to neglect some brothers
Just too many names to cram, but frankly my dear - I don't give a [bad word] 
 [bad word] interlude and knife dance, which ends with the knife down Fester's throat)

Mamushka! Mamushka! He dances the Mamushka!
With a hey and a hey and a hey and a hey
and a hey and a hey and a hey and a hey
andaheyandaheyandaheyandaheyandaheyandaheyandaheyandahey...

WAIT!

I swear by Mommy and Daddums
This detestable Fester's the echt Fester Addams!
So... Hey! Hey! Hey! Hey! Hey! Hey! Hey! Hey!
Let's dance the dance of brotherly love!

MAMUSHKA!
