We live just down the road from Twinsburg (Ohio) and, at least once a year, our town is overrun with hundreds of sets of twins and quite a few sets of triplets. Last year a set of identical triplet girls graduated from our high school. The only way to tell the apart was that they each had a different hair style. I got to know them because they worked on the backstage crew for the high school play (although I never did figure out how to assign the correct name to the correct triplet). The three of them graduated in the top 25 of their class (but not with identical rankings). I never realized just how rare it was to meet a set of identical triplets.
