Don't trust the ID T-shirts—8-year-old identical twins Terri and Sherri Wright of Amory, Miss, sometimes switch just to be devilish—and then even their grandmother can't tell the difference. What matters is that Terri and Sherri, not necessarily in that order, copped the grand prize for lookalikes in the 6-to 12-year-old division at the 45th annual convention of the International Twins Association in Memphis.

"We knew we were going to win all the time," says the one marked Sherri. "We just kept on standing there smiling at the judges," adds Terri. But not too broadly. They know just how far to go in the smile department, because at that critical point the single flaw in their similitude is revealed: Terri's right cheek dimples. Otherwise they are as one. Each is four feet tall, weighs 57 pounds, sings, tap dances, takes ballet, plays piano and likes pizza, strawberry ice cream and Dewayne Hightower, their third-grade classmate. Lucky Dewayne doesn't try to tell them apart. "He just goes with the one closest to him," says Judy Wright, their ex-stewardess mom and a twin (non-identical) herself. "On their birthday, he sent each a Barbie doll." The girls, coached by their father, Charles Wright, a senior medical sales rep for Searle laboratories, have been competing in beauty pageants since they were 4 and are bound for showbiz. Now represented by a New York agent, they just got their first gig, a TV promo spot for the U.S. Navy. But when Cadbury chocolates rejected them because they were blond, Sherri and Terri wound up in identical tears.
