A Phineas and Ferb Family Christmas

The boys decide to put on a traditional family Christmas special featuring their family, friends and a few very special guests, including Kelly Clarkson.

Episode Summary
Phineas and Ferb are lying under the oak tree when Phineas comments that it's hot and suggests they do something to cool off. When Ferb proposes a visit to Antarctica, Phineas turns it down and decides to host a traditional family-oriented Christmas Special that would be broadcasted live on television.

The Christmas Special stars the Flynn-Fletcher family and their acquaintances and features several unnamed extras. Candace, upon noticing the Christmas special, sets out to bust Phineas and Ferb once again. She tries to call Linda, who is shopping, and tells her to shift her attention to a television display to see what her children are doing. However, the special cuts to a toothpaste advertisement before she can see it.

Doofenshmirtz, upon seeing the special, is led to believe that he'd lost track of time and begins to decorate to get into the holiday spirit.

Phineas is dismayed that Perry isn't there to enjoy the holiday with the family. Unbeknownst to him, the platypus was sent to Doofenshmirtz Evil Incorporated by Major Monogram, who himself isn't sure what Doofenshmirtz is up to.

Perry arrives to see his nemesis finishing up decorating the lair for the holidays. He avoids one trap only to be ensnared in gift wrap from Doofenshmirtz's shoulder-fired gift-wrap launcher.

Ferb's Line
(Sings in We Wish You A Merry Christmas)

Perry's entrance to his lair
He enters into his lair and Monogram tells him that Carl is acting as an extra in a Christmas special and sends him to stop Doofenshmirtz.

During the passage "We wish you a Perry Christmas" of We Wish You a Merry Christmas, Perry enters the lair when Monogram and Carl end their line. He starts decorating the lair in a Christmas-style, and after the last "We Wish You a Perry Christmas" he makes his chattering sound and gives a little smirk at the camera.

Background Information

 * "A Phineas and Ferb Family Christmas" features songs from the Phineas and Ferb Holiday Favorites album – Let it Snow, Let it Snow, Let it Snow by Isabella, the Buford and Baljeet rendition of Good King Wenscelas, and the whole gang singing We Wish You a Merry Christmas.
 * This episode is also referred to as "Phineas and Ferb's Family Christmas Special".
 * More of Isabella's family is shown in this episode, including Nana Shapiro ("Lotsa Latkes").
 * This episode happened sometime in July.
 * This episode is sometimes paired with "S'Winter".
 * Isabella wore the most winter outfits than all of her other winter episodes combined.
 * It is possible the line "12th annual Phineas and Ferb family Christmas" reveals Phineas and Ferb are twelve years old.
 * Isabella's hair style is different during the second verse of Let it Snow, Let it Snow, Let it Snow.
 * It is revealed that Irving plays the French horn.
 * This is the first episode that Dan Povenmire directed in Season 3, not counting Phineas and Ferb The Movie: Across the 2nd Dimension.
 * It is unknown why Isabella's lines in We Wish You A Merry Christmas in the Latin-American version were switched.
 * This episode marks the first time Vivian is seen in Season 3.

Production Information

 * This episode aired on Disney Channel (US) on December 2, 2011 right before the premiere of the Disney Channel Original Movie Good Luck Charlie, It's Christmas and right after a special rerun of "Phineas and Ferb Christmas Vacation!".

International Premieres

 * December 4, 2011 (Disney Channel Brazil and Latin America)

Errors

 * Isabella came to the door with Phineas and Ferb to see Kelly Clarkson but after Phineas says "Oh, that's too bad. We'll have a seat, we'll have someone else sing.", she wasn't there.
 * When Major Monogram is singing his part of We Wish You A Merry Christmas, Carl can be seen wearing his Christmas sweater but when it zooms out, Carl is seen wearing his regular clothes again.
 * Before Isabella starts singing "Let It Snow", it is daytime. While she is singing, it is nighttime, but during the last verse and in the rest of the episode, it is daytime again.
 * During the last line of "Let It Snow", Isabella is wearing mittens with her outfit, but when she forms a "heart" sign over the Phineas silhouette on the window screen, she doesn't have any mittens on, but is wearing them again in the next scene. She could've taken her mittens off to form the "heart" sign. And throughout the song, her outfits change.
 * When Irving is playing the French horn, his glasses are green. (This may not be an error. Irving may be wearing green glasses to fit in with the holiday theme.)
 * When Dr. Doofenshmirtz is checking out from the store after finishing his Christmas shopping but is impeded when his Transport-Inator teleports him back to his building, the cashier reports, "Customer Vaporization on Aisle 4," when it happened on a checkout lane. He should have reported "Lane 4" instead.
 * When Baljeet and Buford sing, the piano's sheet has one pieces, but after Buford talks to Baljeet, the piano's sheet has two pieces, and after that the piano sheet's back to one pieces.
 * Olé! isn't a Mexican word, is an Spanish word (of Spain).
 * When Perry flies by the screen in "We Wish You A Merry Christmas," Carl's sweater disappears and is replaced by his lab coat.

Continuity

 * This is the second Christmas episode of the series, but the first to be only 11 minutes long. The first was "Phineas and Ferb Christmas Vacation!".
 * This is the third time the boys do something to cool off. Previously were in "Lawn Gnome Beach Party of Terror" and "S'Winter".
 * Isabella wears similar clothes that she wore in "S'Winter".

Also, this is the 4th time someone of their friends see him ("Undercover Carl", "Swiss Family Phineas", "Phineas and Ferb The Movie: Across the 2nd Dimension").
