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" (¡Olé!) 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

Carl: Sorry, sir...

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

I warn you, my new -inator

Will force you to serve me later

So why not just choose to cater

To my every whim?

All: We wish your every endeavor

Makes this the best Christmas ever

And we're all so glad that we will never

Mention figgy puddiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiing...

Dr. Doofenshmirtz: ''Oh, great. Well now we've mentioned it.''

Major Monogram: You know, no one would have noticed if you'd have just kept your mouth shut.

Background Information

 *  is a popular secular sixteenth-century English carol from the West Country of England. The origin of this Christmas carol lies in the English tradition where wealthy people of the community gave Christmas treats to the carolers on Christmas Eve such as "figgy puddings" that were very much like modern day Christmas puddings. It is one of the few traditional holiday carols that makes mention of the New Year celebration. The song is often parodied.
 * The Phineas and Ferb Holiday Favorites album lists "The Cast of Phineas and Ferb" (or Cast - Phineas and Ferb) as the song's singers.
 * The third song with more singers ("A-G-L-E-T", "The Twelve Days of Christmas"), It's the second to appear in an episode.
 * This song speaks more of Isabella's family, showing she has relatives from Mexico and Jerusalem.
 * The "calculator-slash-Hindi-English-translator" Baljeet mentions may be the one that he gets from Buford (and is automatically smashed by Buford's baseball bat) in "Phineas and Ferb Christmas Vacation!".
 * Before "A Phineas and Ferb Family Christmas", a music video using a combination of clips from the series combined with some created for the video was aired. It debuted during the opening of the Disney Store in New York City on November 9, 2010. It also aired on Disney Channel November 26 @ 8pm during the premiere of The Suite Life on Deck episode of I'm in the Band. The music video was also seen on Disney XD UK on December 20, 2010. The "Happy Holidays from Phineas and Ferb" scene at the end was cut. The Disney XD logo was seen when the music video played.
 * The first section of Isabella's line was skipped when it played on Disney Channel.
 * When Buford sings his lines (and gives Baljeet a wedgie), he and Baljeet are in a Nativity Play; Buford playing as the angel and Baljeet playing as the shepherd (in the Gospel of Luke), who was visited by the angel after Christ was born.
 * Isabella sings the song even though she mentions that she doesn't celebrate Christmas.
 * Second time Isabella sings her catchphrase, the first being her song in The Dad-inator. This is also the 2nd time she sang it in an episode, the first being "What'cha Doin'?" in "Rollercoaster: The Musical!"
 * This song has background vocals by Laura Dickinson (http://ringostrack.com/en/artist/laura-dickinson/15684)

Continuity

 * Though not the Phineas and Ferb version of the song,  was sung by carolers to force Heinz Doofenshmirtz into giving them figgy pudding in the Season 2 episode "Phineas and Ferb Christmas Vacation!".
 * Isabella says in "Phineas and Ferb Christmas Vacation!" that she doesn't celebrate Christmas, though in the song, she sings about celebrating it with her family.

Errors

 * When Major Monogram had complained about Carl, he wore a sweater, but after Perry came, he wore his normal stuff.
 * When Phineas and Ferb grab their presents at the beginning of the song Phineas is on the right and Ferb is on the left, but when the scene changes they switch sides.
