As identical twins, Diane and Darlene Nettemeier have a lot in common. In fact, their husbands look exactly alike—they're twins, too.

Years ago, the sisters attended a twins' festival in Ohio. It was there that they met Mark Sanders—a handsome man who was also an identical twin. Upon meeting the women, Mark called his brother Craig, who was up in his hotel room. Craig recalled the love-at-first-sight moment:

"When I went downstairs I was instantly attracted to the one on the right," Craig said on the Jeff Probst Show. "Diane was standing on the right, and Darlene was standing on the left, and I was instantly attracted to Diane."

After meeting at the festival, Mark and Craig made plans to visit the ladies in St. Louis, where the four of them went on a double date to a baseball game.

Soon after, Craig and Diane and Mark and Darlene married in a joint ceremony. At this point, it was just plain appropriate—both couples were engaged on the same day, too.

"We had a double wedding and Darlene and I decided that we wanted to wear the same dress and then our dad walked us both down the aisle at the same time," Diane said.

Then, in 2001, Diane and Craig gave birth—to identical twins.

"When you throw in a third set of identical twins, that makes it even more unusual," Mark said.

The Sanders families now have five children between them, and they live right next door to each other.

Here's wishing them the best. Here's wishing them the best.
