What do Alanis Morissette, Montgomery Clift, and Theo Epstein have in common with Tiki Barber, Minnesota's professional baseball team, Fred and George Weasley, and two of the Bee Gees?

They're all twins! And for over 30 years now, twins of all ages have been flocking to  -- where else? - Twinsburg, Ohio every August, to celebrate a weekend of this special sibling bond. The town of Millsville was settled in 1819 by Connecticut twins Moses and Aaron Wilcox, who renamed it Twinsburg, spent the rest of their lives together, and are buried there. Over 3,000 sets of twins will increase Twinsburg's population by nearly 50% this weekend!

We all know at least one or two sets, so best wishes -- times two -- to all twins and multiples on this Twins Day weekend!
