Carol Connors and Thora Birch
Did you know that Carol Connors (pictured above), major adult star of the 1970s who starred in both Deep Throat (the highest grossing film of ALL time, including Jaws and ET and all those others) and the Erotic Adventures of Candy, is the mother of Thora Birch of Ghost World and American Beauty (below)? Thora's dad was Jack Birch, an adult film star in his own right.
Imagine having porn stars for parents. What would you have to do to get them to disapprove and eventually disown you?
