Terri Mackleberry

“Isn't it amazing the same day you got a pool is the same day we realized we liked you?”

―Sherri^[src]

“The timing worked out great. Don't you think?”

―Terri^[src]

“You ruined our undefeated season. You ruined everything, ruiner. ...My sister likes you.”

―Sherri^[src]

Terri Mackleberry^[1] is the younger twin-sister of Sherri Mackleberry. She is in the same class with Bart Simpson at the Springfield Elementary School.

Biography

They are quite bright students (they even have their own twin language commonly known as Cryptophasia) and are often very conniving and mean, even to each other. When it comes to Bart they are quite stuck up, and never miss an opportunity to berate him. Bart appears to have a crush on one of them,^[2] but Homer states that Terri is the one that Bart has a crush on.^[3] One of the twins stated that her sister had a crush on Bart. It is unknown if this is the truth or if it is just teasing.^[4] She also has a "boy crazy" cousin who has a crush on Bart. (Bart feels affection for her and she may also feel affection for him).

When it comes to Lisa Simpson they are just as inconsistent. One minute they will be friends on the schoolyard playing together and the next they will be ganging up on her. More often than not it is the latter, usually not including Lisa because she is too smart or too weird. It is implied that she and Sherri are actually two out of three triplets who were conjoined and it is said the third triplet is trying to kill them, but that can be viewed merely as a throw-away joke by the writers, and should not be regarded as canon.

Principal Skinner apparently considers Terri less smart or talented than Sherri, because in Simpson Tide he announces, "In the event of nuclear war, we can only save our best, and brightest. Therefore, space in the fallout shelter will be reserved for: Lisa Simpson, Martin Prince, our championship kickball team, and Sherri, but not Terri." Both the twins Sherri and Terri have creamish-like pale-yellow skin and dark bright purple hair.

Future

In "Barthood", it is revealed that in the future, Bart enters a relationship with Terri. When he throws a party, he accidentally makes out with Sherri who remarked he kisses just like Terri said. He is shocked and asks, "Wait, you're not Terri?" and awkwardly backs away when Sherri tries to continue the encounter. It is unknown what became of this relationship. ^[5]

Nelson Muntz simultaneously dated and impregnated both Terri and her sister, who bore him four children (two sets of twins, naturally) shortly before Nelson's high school graduation. It's implied that one of the twins tricked him into thinking he was with the other. He abandoned them during Bart's graduation party, using the same statement his father said to him before abandoning him.^[6]

Treehouse of Horror series

Treehouse of Horror XIV

She and her twin are seen at the school assembly behind Bart and Milhouse.

Treehouse of Horror XXVII

In the second segment BFF R.I.P., after Janey Powell is killed by Ned Flanders' lawn mower she and Terri tells her that losing her best is a life on tragedy, which that she can be their new best friend for life. However, they are killed by a falling tombstone.

The Simpsons Arcade game

Sherri and Terri appear in stages 1 and 2 carrying a burger in a plate for the Simpsons to gain their health.

The Simpsons Game

Mob Rules

Sherri and Terri appear with an Itchy mask and act as enemies that must be defeated.

Big Super Happy Fun Fun Game

Sherri and Terri also appear as one of the holders of the three Sparklemon that Homer and Lisa must defeat.^[7]

"The Simpsons Guy"

At the special's climax, Homer and Peter Griffin engage in a lengthy chicken fight, and they knock over some students who are waiting at the bus stop (including familiar characters like Milhouse and Martin). Sherri and Terri are knocked into the street and then hit by Otto's bus, sending the twins flying off-screen.

Behind the Laughter

Creation

They have similarities to the Grady Twins (ghost girls) Danny sees in Stanley Kubrick's adaptation The Shining, of Stephen King's The Shining novel of the same name. In a deleted scene of the parody of the Shining called "Treehouse of Horror V" they are ghost twins seen by Bart. They also take on this role in The Simpsons Game were in a game engine elevator they are heard saying "Come Play With Us Simpsons". She is said to be the taller of the two.

Trivia

Terri is the one on the right as it was stated by Matt Groening that Sherri is always on the left.
Both she and Sherri bear some resemblance to the twins Patty and Selma, as both hold an enjoyment for tormenting the males of the Simpson family, but for different reasons, and have a close relative who have a crush on one of the Simpsons.
It is implied that Sherri and Terri aren't actually twins, but 2/3rd conjoined triplets. This has to be considered just a throwaway joke by the writers, as this 'third triplet' has never been shown or mentioned before.
Sherri and Terri's last name was finally revealed in the new episode "Yellow Subterfuge", written on Principal Skinner's list of students.^[8]
On November 10, 2019, Al Jean announced via Twitter that Grey DeLisle assumed the roles of Terri, Sherri and Martin Prince, starting with the episode "Marge the Lumberjill", following Russi Taylor's death earlier in the year.^[9]
