Identical Twin Couples Take Their Relationships To A New Extreme

Did you know there's such a thing as a twin convention? Neither did we. Though it's a common stereotype that twins look, think, and act the same way, some sets of doubles actually do (and it's a bit spooky). Take identical twins Darlene and Diane, for example; their identical lives were changed forever after attending a yearly Ohio twins festival in 1998. You're not seeing things — these twins are just this extreme!

Attached at the Hip

Born 45 minutes apart, identical twins Darlene and Diane Nettemeier grew up in Illinois doing just about everything together. Though they weren't conjoined twins, they were attached at the hip. They shared friends, clothes, hobbies, and that lasted into adulthood. They couldn't see spending their lives apart... so they didn't.

D & D

In fact, throughout their lives, Darlene and Diane haven't spent more than one week apart from each other! And on one of their many twin-tastic adventures, this one taking place in August 1998, the girls took a trip to the annual Twins Days Festival in Twinsburg, Ohio. They knew a wild time was in store.

Twins Days Festival

Known to be "the world's largest annual gathering of twins," the Twins Days Festival, which took place at a hotel, was the perfect place for Darlene and Diane to bask in the joys of having a near carbon copy by your side. But the dynamic duo had no idea that it would be a day for the history books.

Gaga for Mark

In the hotel bar, the sisters conversed with a cute, chestnut-haired guy named Mark Sanders, whom Darlene was particularly fond of. The chitter-chattering was going well, so Mark bolted to get his identical twin, Craig Sanders. "I had to go get him because otherwise I was afraid they were going to be scared I was some single crashing the twin party," Mark told NBC's Savannah Guthrie.
