Here’s a story, of a lovely lady, who cheated on her hubbie and got…crabs?

Florence Henderson, the iconic mother of The Brady Bunch, is publishing a memoir in which she admits she cheated on her husband in the 1960s with John Lindsay, the then Mayor of New York City.

“I was lonely. I knew it wasn’t the right thing to do,” the actress writes in Life is Not a Stage, her  memoir to be released September 20. But that’s not where the story ends…

Henderson awoke the next morning in the Beverly Hills Hotel to “little black things” crawling over her bed and body and was later diagnosed as having a pubic lice STD.

Henderson says: “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.”

Ahm, did you say, Relationship?
