3 Grannies Critique 'Fifty Shades Of Grey' (VIDEO)

They're baaaack!

The three outspoken sisters -- who are best known for their assessment of Kim Kardashian's sex tape (and lack of carnal moves) that went viral in May -- have a few things to say about the runaway S&M hit novel "Fifty Shades of Gray." (Warning: The video above includes graphic sexual language.)

"I think this is the best way to lose your virginity and then quit," said Josie Cavaluzzi, 72.

"I spoke to a lot of women, younger women in their 30s, and they absolutely can't put this book down," shares Mary Bartniki, 81. "I'm puzzled! I don't know why."

The 3 Golden Sisters, as they're now known, hoot, cringe and shake their heads at some of the more raunchier acts and "contracts" described in the book's pages.

"No acts involving fire," reads Teresa Dahlquist (Josie's twin sister).

"Well, of course not," agrees Cavaluzzi.

But for all their admonishments, the book's leading man gets the 3 Golden Sisters' seal of approval. "Oh my God!" Dahlquist says, passing over an iPad. "He sounds like a good lover!"
