Who are Sherri and Terri?
Sherri and Terri Mackleberry are identical twin sisters, students at Springfield Elementary, in Bart's class taught by Edna Krabappel. Long purple hair, pale skin and identical outfits: everything is designed so that you cannot tell them apart. Their parents have no canonical first names in the series; their father even appears as one of Homer's supervisors at the nuclear plant.
🧦 Long purple hair, identical outfits: at the Mackleberrys', good luck telling which one is Sherri. At the bottom of your drawer, our Simpsons socks work on the same principle: two perfectly matched twins, one for each foot.
Two (almost) impossible-to-tell-apart twins
The twin act is part of the character: they are almost always together, often speak in unison and even have their own language. The only canonical detail that separates them: Sherri is the elder... by two seconds.
📱 To tell Sherri and Terri apart, the show leaves just one canonical detail: Sherri is the elder by two seconds. When your Samsung looks exactly like your neighbor's, our Simpsons Samsung cases give you a far more visible marker than that.
The troublemakers of Bart's class
Do not be fooled by their well-behaved air: they are genuine troublemakers. They happily torment Bart — whom they regularly mock — while playing the angels in front of their teacher. A double game that makes them the quiet queens of schoolyard mischief, alongside Lisa and the other students.

🧢 Same dress, same hair, same scream: in the schoolyard, nothing gives away which one is Sherri and which one is Terri. All you need is a brim of your own, picked from our Simpsons caps, and you'll be spotted at first glance.
The twins' voice actors
In the original version, Sherri and Terri were long voiced by Russi Taylor (until her death in 2019), before Grey DeLisle took over the role. In the French version, Régine Teyssot lends them her voice; their first names are kept as they are.
