Brady Bunch mom got crabs in affair with NY mayor

Revelation: Florence Henderson claims she caught crabs

after having sex with politician John Lindsay in the 1960s

This would have made an interesting episode of "The Brady Bunch."

Florence Henderson, the actress who played perky mom Carol Brady in the beloved family sitcom, says she once got crabs after a one-night-stand with career politician John Lindsay, who was the mayor of New York City at the time.

Henderson, now 77, recounts in her upcoming memoir that she was cheating on her husband during the 1960s, and gave in to her better judgment when her married and unattractive friend put the moves on her over drinks at the Beverly Hills Hotel.

"I was lonely. I knew it wasn't the right thing to do. So, what did I do? I did it," she writes in "Life is Not a Stage," set for publication in September.

Henderson went home later that night, and awoke to a grisly surprise the next day as she saw "little black things" crawling over her bed and body.

An urgent call to a doctor took care of the problem, known medically as pubic lice, and Lindsay sent her flowers and a note of apology.

"Guess I learned the hard way that crabs do not discriminate but cross over all socioeconomic strata," Henderson writes. "He must have had quite the active life. What a way to put the kibosh on a relationship."

Lindsay, who died in 2000, was mayor of New York from 1966 to 1973. Before that, he was a U.S. congressman. He launched a brief bid for the Democratic presidential nomination in 1972. His wife of 51 years died in 2004.
