Identical Cousins: The Patty Duke Show
by Bambi Turner
Patty Duke was such a big star in the '60s that she not only got her own show -- she got to play two different roles in the same series. In a "Parent Trap" -esque scenario, Duke played the wild and crazy Patty and her lookalike cousin, the much calmer Cathy. Take our quiz to see how much you remember about this classic comedy!
