For a long time, I didn't know Jamie Lee Curtis was the daughter of Janet Leigh and Tony Curtis. And Ben Stiller/Jerry Stiller/Anne Meara was surprising as well.

More recently, Demi Lovato and the girl from Desperate Housewives. And just this week, I found out Freddy Rumsen from Mad Men is Bill Murray's brother.
