John Reznikoff is listed by the Guinness people as having the world's largest collection of hair from historical figures and celebs. He says one of his prized possessions is a lock of Lincoln's hair, cut the night of the president's assassination. The Connecticut collector admits some might think his hair clippings are kind of creepy. But he says someday his collection of locks could help unlock the secrets of DNA. [Ed. note: as any fan of CSI knows, you need a hair follicle ("tag") to get DNA.]
