"Hi, Eddy. We're going to be in math class together again this semester, aren't we?"The previous semester Eddy Galland was a student there.And to scientists who studied them, they had similar personalities: they were talkative, and they laughed a lot.Studies with twins like the Giggle twins seem to make tase far treredity, don't they?Because of this, they were called the "Giggle" twins. Scientists like to study such cases of twins. They want to answer the classic question, "What's more important--heredity or environment?"Bobby Shafran started a new semester at Sullivan Community College in New York.After the story was in the newspapers, another boy, named David Kellman, realized that he was their brother, too-also born at the same time.Another well-known story of twins is that of Daphne Goodship and Barbara Herbert.Well, perhaps, that isn't very surprising, is it?But are all the similarities just coincidences?"Sorry, I'm not Eddy.""You're Bobby, aren't you?""No, I am not. I'm Eddy."Three brothers--triplets--met for the first time at the age of 19.The two teens looked exactly alike.That student introduced Bobby to Eddy.So, the twins became triplets!
