In her forthcoming memoir, the actress best known for playing the mom on The Brady Bunch revealed a few new details about her good buddy, now-dead New York City mayor John Lindsay. Like that he gave her crabs after a pity one-night stand she had with her “married and unattractive friend” one particularly lonely evening in Beverly Hills. “Guess I learned the hard way that crabs do not discriminate but cross over all socioeconomic strata. He must have had quite the active life. What a way to put the kibosh on a relationship,” she writes. Henderson also added the detail that Lindsay “sent her flowers and a note of apology,” lest you get the impression she was trying to tarnish his good name out of revenge for some gross problem he saddled her with or something.
