Finding Mary McGuffin

Dad, is that the box from my room? I think I put my Mary McGuffin doll in there by mistake!

When Lawrence accidentally sells Candace's doll to Doofenshmirtz, Phineas and Ferb become detectives to try and find it.

Episode Summary
At the Flynn-Fletcher house, Lawrence and Linda are putting on a yard sale. It turns out that Linda was going to sell her Lindana records but snatched them from a man who was looking at them. Phineas and Ferb ask Lawrence if they could watch his black and white detective films. Lawrence allows them when Heinz Doofenshmirtz appears at Lawrence's stall. He buys a Mary McGuffin doll and walks off. Candace appears a minute later and asks Lawrence if he has seen her Mary McGuffin doll. Lawrence says he just sold her for a dollar and asks if Candace wants it. She screams and Lawrence offers her two dollars.

Doofenshmirtz arrives at Charlene's house and asks for Vanessa. Doofenshmirtz hands her the doll and talks about how he's been searching for years for the doll. Vanessa, surprised at her dad's act of love thanks him and walks to her room to think. Meanwhile, Phineas and Ferb are influenced by the detective films and turn themselves and everything else black and white. Candace tells them about her doll and Phineas decides they will investigate.

In The Agency, Major Monogram is seen playing a video game. Perry is waiting for his assignment. Monogram tells him that Doofenshmirtz has been to a yard sale, bought an Inator and a box of 'on-off' devices. Carl tells him that they're called 'switches'. Perry's chair turns into a big ball (like a bowling ball) and rolls down a chute.

The boys and Candace interview Lawrence, asking him who he sold the toy to. Lawrence tries to describe Doofenshmirtz, 'German accent, lab coat'. Phineas and Ferb go to a lab coat shop and interrogate people there. One of the men says he doesn't know anything but then Ferb 'leans' on him. He tells them there is a guy who puts all of the costs on his ex-wife's tab. He gives them the address and Phineas tells Ferb to pack up the studio.

Back in Vanessa's room, she starts thinking about the times her dad has embarrassed her and times when he has made her day. She really appreciates her gift and puts it on her shelf with her other toys. When she closes the door, the doll falls near a box of junk. Vanessa walks downstairs, unaware of what happened and logs on to her laptop. Charlene answers the door and it is a man who works for Charitable Charities. Charlene asks Vanessa where her box of junk was and she goes to Vanessa's room. She assumes that the Mary McGuffin doll is part of the junk and puts it in the box. Charlene hands the box to the man and he puts it in the truck. Vanessa realizes that her doll was in the box and runs after the man just as Phineas, Ferb and Candace walk up to her house. Phineas interrogates Charlene and she tells them that the doll was in the box to be sent to a Charitable Charities somewhere. The group start looking around all of the Charitable Charities around but can't find Mary.

Doofensmirtz is in his building and has bought lots of things from yard sales. He is trying to find a switch to fit his Inator when Perry comes in. Doofenshmirtz activates the lobster trap that he got for free and tells Perry what he is doing. The switches he tries are too big or too small until he comes across the right one. He places it upside-down and complains that the writing is even printed upside-down. Doofenshmirtz realizes he put it upside-down and turns it around. He then turns on his invention but Perry's trap opens. Perry climbs out whilst Doofenshmirtz is still wondering why the Inator isn't switching on. He then turns around and sees the switch opening and closing the trap. He now knows why the trap was free. After a brief fight, Doofenshmirtz realizes that he can't do anything evil with a machine that just opens and closes a lobster trap so Perry can go home. Perry gives a thumbs-up to Doofenshmirtz and leaves.

Phineas, Ferb and Candace are in the last Charitable Charities shop when Candace spots Mary McGuffin. Candace grabs the doll at the same time Vanessa does. They fight over the doll and the doll flies into the air into Sally's hand. She instantly loves it and Candace says she's too old for dolls now. Vanessa wonders if she should give up the one thing that proves how much her dad cares for her, then snatches it from Sally's hands. Sally starts to cry. Vanessa phones her dad, while he's cutting a carrot. He's proud of Vanessa for committing an evil act and says that they could build on this.

 * Doofenshmirtz Evil Incorporated! spoofing "We Won't Get Fooled Again" by The Who, the theme of the TV series CSI: Miami

Background Information

 * When Doofenshmirtz screamed "Score!" he looked right in the camera, breaking the fourth wall.
 * Ferb, however, didn't react being in love when he saw Vanessa in this episode, but, when Vanessa goes out of her home, Ferb stares at her.
 * While Charlene was listening to Vanessa complain about her doll being missing, she seemed to be reading the same book Ferb is usually seen reading.

Production Information

 * This episode premiered in the UK on October 18, 2009 at 9:30 a.m.(British Summer time) on Disney XD.

Errors

 * When the lobster trap falls on Perry it opened and closed from the bottom. When Doofenshmirtz was accidentally opening and closing the trap, it opened from the top.
 * When Phineas and Ferb are talking to Vanessa's mother, Ferb's left eye (the one facing us as viewers) is bigger.
 * When Ferb packs up the interrogation scene in the Labcoat Emporium, the table and chair folds with it, yet when he packs up the interrogation scene after questioning Vanessa's mother, they remain unfolded.
 * When Doofenshmirtz said he didn't understand why the lobster trap came free with the Inator, surely he would have noticed the cable connecting the two of them when he bought it.
 * Vanessa calls the Mary McGuffin doll a "piece of plastic" ("Not So Bad A Dad") When the doll is a plush doll.

Continuity

 * During the fight between Doofenshmirtz and Perry, the Doof 'N' Puss Theme Song from the future Season 2 episode, "Nerds of a Feather" is heard.
 * Doofenshmirtz mentions his Lawn Gnome flashback from "Lawn Gnome Beach Party of Terror", and that he purchased his degree, a fact first revealed in "I Scream, You Scream".
 * Lindana's record is seen among the records at the start. In fact, it's the exact same record shown in "Flop Starz". The elevator music version is heard during that scene.
 * Vanessa was expecting a car, just like she asked of Doofenshmirtz before in "Vanessassary Roughness".
 * The man with the accent, who also appears when Doofenshmirtz "goes out of his way to catch that foul ball", is one of the people watching the concert Phineas and Ferb host to bring home Perry in "Oh, There You Are, Perry".
 * Unnamed Charitable Charities worker who asks Phineas if he is too young to know about "all these old detective films" looks eerily similar to the worker who listed the climbing toys (Climbin' Simon, Ascendin' Brendon, Ladderman Larry, Climby Jaimie) in "Toy to the World". This man was also used for "Unfair Science Fair" and "What Do It Do?".
 * During the scene where Doofenshmirtz "wore all that fringe" in Not So Bad A Dad, Doofenshmirtz is wearing the same outfit he wore from when he was singing Yodel Odel Obey Me in "Bubble Boys".
 * Phineas and Ferb are wearing the same sunglasses they wore during History of Rock from "Dude, We're Getting the Band Back Together".
 * The Retro Pharmacist Emporium from "Run Away Runway" was seen in this episode.
 * The 70's style music from "Isabella and the Temple of Sap" is heard.
 * Ben Baxter from "Flop Starz" reappears.
 * Heinz mentions that Perry has keys to Doofenshmirtz's house. He mentioned this in the earlier episode "Lights, Candace, Action!"
 * Monogram is seen playing video-games like in "That Sinking Feeling".
 * Vanessa is listening to I'm Me from "Vanessassary Roughness".

Allusions

 * During the montage of Charitable Charities interviews, several detective parodies are seen, including Starsky and Hutch, Miami Vice, and CSI: Miami.
 * Starsky and Hutch - Though the car driven by Detectives Ken Hutchinson and Dave Starsky was a 1974 Ford Gran Torino, the one driven by Phineas and Ferb was an AMC Javelin.
 * CSI: Miami - Phineas did Horatio Caine's sunglasses gag and the screaming where the boys are traveling on the air-boat is the same as the start of its theme tune, Won't Get Fooled Again by The Who.
 * The title and doll refers to a MacGuffin, a term coined by Alfred Hitchcock to describe a common item whose single, sole purpose is to drive the plot of the episode forward, either directly or indirectly. The Macguffin Doll would be a good example of said object.
 * Cherry Merry Muffin - "Mary MacGuffin" doll may be in reference to the popular "Cherry Merry Muffin" dolls of the 80's.
 * Cabbage Patch Kids - The scarcity of the Mary McGuffin doll is like that of the Cabbage Patch Kids dolls of the early 1980s. The manufacturer was not prepared for the overnight popularity of the doll, so store riots broke out as parents fought over the small supply of that year's must-have Christmas gift.
 * Family Guy - The lost doll plot is similar to Family Guy episode 'Road to Rupert', which Dan Povenmire directed.
 * Rugrats: All Grown Up - The Plot is also similar to an episode of the Nickelodeon show Rugrats: All Grown Up, in which Angelica Pickles loses her Cynthia doll after her mom sells it, as well as an episode of Disney Channel's Even Stevens called "Where in the World is Pookie Stevens?" in which Ren's Pookie doll accidentally drops into a box that is taken down to their family's yard sale and prompts her younger brother to search for it.
 * The title is similar to Disney/Pixar's hit Finding Nemo.
 * Finding Mary March - The title is similar to this minor 1988 movie. Mary March seems to have started the title trend of: Finding + someone.
 * When Vanessa recalls her dad going "out of [his] way to catch that foul ball," they are shown in the first row along the left field side at a baseball game, robbing a player in white with a blue hat and sleeves from making a catch in foul ground. This is a clear reference to the Bartman play in Game 6 of the Cubs/Marlins 2003 NLCS series.
 * The music when Phineas and Ferb visited the first Charitable Charities location, the music founded familiar to the song Racetrack 3000 by The Swivelheadz.
