Lincoln hatches a plan to capture the "perfect" family photograph for his parents' anniversary gift.
Lincoln has created a homemade coffee mug as an anniversary gift for his parents every year, but his sisters believe it to be a lame gift, with Lola accidentally blurting out that Mom and Dad put his "mugs" in the attic without his knowledge. When he goes into the attic to see if this is true, he discovers that Lola was right, as all the "mugs" Lincoln made in the past are stored away. As a heartbroken Lincoln worries about what he can give to his parents now, he finds Dad's old camera, and gets the idea to take a family portrait to give to his parents.
Lincoln gathers the girls in the backyard for the photo shoot, and they all hold a smile, as Lincoln sets the automatic timer. However, they get bored after a few seconds and go do their usual antics, as the picture gets taken, much to Lincoln's frustration. Feeling the photo isn't "perfect", Lincoln uses various methods to convince his sisters to take part in a new photo. As he does, he alters their appearances, stifles their natural habits, and puts matching sweaters on them.
As the timer is set, Lori asks Lincoln what was wrong with the other photo and he nervously admits that they acted too much like themselves. Everyone is deeply offended by his thoughts of them, so they decide to put on "perfect" smiles for the camera out of spite for him. After the camera takes the picture, the girls leave Lincoln, apparently in a flash. As Lincoln walks through the house, looking at the new picture and observing his sisters' true personalities, he sees how happy they are and begins to realize that his new picture of them doesn't reflect on who they really are.
When the time comes to give Mom and Dad their present, Lincoln ends up giving the old photo instead of the "perfect" one. They love it so much that they decide to hang it above the mantle for all to see. Lincoln apologizes and says to sisters that their true selves are perfect enough for him, and they embrace in a group hug. However, as a final rub-in, Lincoln tells them they might as well put their gifts in the coffee mug box, since their gifts will pale in comparison to his, which angers them into arguing with him... just the way he likes it.

Lincoln's first attempt to take the perfect family picture was used in one of the early promos for the show.
Things the siblings and pets were doing that messed up the photo:
Lincoln - Shouting in frustration.
Lori and Leni - Using their cell phones.
Luna - Playing guitar.
Luan - Wearing her funny glasses.
Lynn - Playing with her football.
Lucy - Reading.
Lana and Lola - Fighting.
Lisa - Reading off a clipboard.
Lily - Running around naked.
Charles and Cliff - Playing chase.
Geo - Running around in his ball.
Walt - Flying around.
The ways Lincoln altered the Louds’ appearances:
Leni - Put Lisa’s glasses on over her eyes to make her look sharper
Luna - Added a wig to hide her pixie cut, which Lincoln claimed was a bad hairstyle
Lana and Lola - Inserted jumbo-sized marshmallows where their missing incisors should be
Lisa - Put Leni’s sunglasses on over her eyes to make her look cooler
Lily - Taped her diaper to her body and made her suck on a pacifier with teeth painted on it
The things for which Lincoln's sisters mistook his coffee mug:
Lori - A paperweight
Luna - Shirley
Lynn - A pencil holder
Lucy - An inflamed liver
Lisa - A bust of Immanuel Kant
Picture Perfect - The title of this episode means having an appearance or quality that is exactly right.
Peanuts - The music played during the title card is reminiscent towards the franchise. It also has a similar tune to the song "With A Little Help From My Friends".
Diary of a Wimpy Kid: The Long Haul - The pacifier that Lincoln gave to Lily for the family picture is similar in appearance to Manny Heffley’s pacifier from this 2014 book by Jeff Kinney.
Immanuel Kant - Lisa thinks that Lincoln's coffee mug is supposed to be a bust of this German philosopher.
When the siblings are smiling for the first picture, Lola appears to be missing one of her lower teeth.
Lincoln's chipped tooth is replaced with normal looking front teeth when they smile for the second picture.
When Lynn says that the "coffee mug" is a pencil holder, part of her hair is missing.
After Lincoln makes Lucy smile for the second picture, Lily's pacifier is different as it's missing the mouth on it.
When the kids shout out "Happy Anniversary!", Lucy was on the left side, but then appears on the right.
When Lola reveals that Mom and Dad hide all of Lincoln's gifts in the attic, Luan's buck teeth and braces are missing.
Also, Lincoln's chipped tooth is missing and his teeth don't have lines.
Lucy’s skin is also less pale.
Plot hole: In this episode, Lori seems to be aware of what the Mona Lisa is, even though in "The Green House" she is completely clueless on what it is. It's possible that it took place before this episode.
