Being an identical twin is kind of like having a parallel world right on top of ours, one in which there is another version of you running around. Dana Chivvis has the story of the Sklar twins, and a 48-year-old mystery. (19 minutes)
Ira Glass speaks with a woman named Angie, who never understood why her dad got so excited about thermoses and phone books... until she happened to see this one movie. Then Jonathan Goldstein tells a story about his friend Josh Karpati, who has two-year-old twins, and who never leaves the house.
