Nov. 14-20: The Beatles reunite, Princess Di spills the tea, Michael Douglas is the fairytale president, Homer meets his mom, Robert Downey Jr. is the worst P.I., a very stoned Christmas Eve, Tom Hardy is twins, South Park is trapped in the closet, and a Christmas romance you won't see on the Hallmark Channel. All that and more from 30, 20, and 10 years ago.
