Jason Merritt/Getty ImagesFlorence Henderson, best known as Mrs. Brady, has written a book titled Life Is Not a Stage. Florence didn't dedicate the entire book to behind-the-scenes Brady dirt, only taking the time to clear up the old rumor that she was not porking Barry Williams, who played Greg. Thanks for ruining my fantasy, girl. Apparently Florence was a bit of a dirty girl and admits in the book to cheating on her husband in the '60s. She claims that she had a one-night stand with former New York mayor John Lindsay...and that he gave her crabs. She said that she woke up after the one nighter to find "little black things" all over her bed and body. What...a revelation. I've had a similar experience, but it was only one black thing and it wasn't little.
