Oh, the guv'ment's got a great cloning operation goin' on, has done for years. Lots times the clones themselves have no idea they're clones, even when people tend to jokingly or mockingly call them clones, sometimes. The reason people don't catch on is because they're not exact clones. i.e., they don't really look or sound or anything, exactly like their progenitors. Here, I'll let you know of what few I'm aware of, positively...

Oasis = Beatles

LeAnn Rimes = Patsy Cline

Kate Mulgrew = Kate Hepburn

Dakota Fanning = Tilda Swinton

more to come...
