It's unusual enough to be identical twins, but for a pair of such twins to meet another pair of identical twins and fall in love? That's gotta be pretty rare. But then, for one of those couples to give birth to identical twins, that's even more of a rarity. But even the rarest of events can still occur. And so we have the case of Diane and Darlene Nettemeier and Craig and Mark Sanders.

The two sets of identicals met at the Twin Day festival in -- where else? -- Twinsburg, Ohio back in 1998. They ended up going on a double date to Las Vegas where they won a whole mess of money playing poker. Sensing they were on a roll, they got engaged the same day. After getting married, they built a pair of homes right next door to each other.

As if all that weren't enough, Craig and Diane went on to have a pair of identical twins of their own, seven-year-old Colby and Brady. And now, ten years after their first meeting in Twinsburg, they're returning to show off their own set of double trouble. I have to say, that's pretty cool. Double cool, even.
