Lyrics:

All: We wish you a merry Christmas
We wish you a merry Christmas
We wish you a merry Christmas
And a happy new year

Phineas: We wish you the best day ever
And hope all your Christmas endeavors
Are super-fun, amazing, and clever
And that your New Year's rocks, too

Isabella: Oh, come tell me what'cha doin'
All my relatives just flew in
From Mexico and Jerusalem
For the holidays

Both Christmas trees and menorahs
It can be confusing for us
When we break into a chorus
Of "olé" (iOlé!) and "oy vey" (Oy vey!)

Major Monogram: Good missions I'll give
To Agents A through Z
Carl, get away from that punch bowl
I'm saving that for me

All: We wish you a Perry Christmas
We wish you a Perry Christmas
We wish you a Perry Christmas
And a (Perry chatters) new year

Baljeet: I wish for a calculator-
Slash-Hindi-English translator
To find a common denominator
In both of my tongues

Buford: Good wedgies I'll give
To all of you nerds
That's how I say "Merry Christmas"
I ain't good with words

Dr. Doofenshmirtz: I wish you would let me rule you
In evil I'm going to school you
I won't sugarcoat or fool you
Your New Year's looks grim

All: We wish your every endeavor
Makes this the best Christmas ever
And we're all so glad that we will never
Mention figgy pudding...
