Celebrities Poking Fun at Celebrity Books

June 24, 2010— -- Ever wonder what it would be like if America's most famous mom, Florence Henderson, channeled Madonna?

Look no further. Henderson is the latest star to poke fun at celebrity books using the celebrities' own words in the hit stage show "Celebrity Autobiography."

On Monday night at Santa Monica's Broad Stage, "The Brady Bunch" mom read aloud a passage from Madonna's book "Sex" about the singer's one-night stand with a teenager.

"I was so turned on; it was probably the most erotic sex I ever had," Henderson read. "But he gave me crabs."

"The reaction was very loud, very responsive," the show's creator, playwright Eugene Pack, told ABCNews.com. "A lot of jaws dropped. It just kind of threw the whole city on its side for that moment."

Apparently, Henderson loves throwing people who often mistake the frisky actress for the honest-to-goodness mom she played on television.

"If I say something, people laugh so hard when it's off-color, and I think it's because of the way I look and people don't expect it. They don't expect me to say the things Madonna wrote in that book," she told the Los Angeles Times.

"I love to shock people," she added. "And when I got to the part about the young man, I thought, 'Everybody's going to be thinking about Greg Brady.' I know some people were thinking that, but that's OK. It's fun!"

Henderson was referring to her famous "date" with Barry Williams, who played her son on "The Brady Bunch." She indulged the then-15-year-old's crush by accepting a date to an L.A. nightclub and even kissed him goodnight.
