Dawber said Williams would grab her breasts and her buttocks, expose himself, wrestle her to the ground and break wind on her on the set of their hit sitcom. She made her comments in the new book Robin, the Robin William biography from New York Times writer Dave Itzkoff. "I had the grossest things done to me - by him," she says, according to The Daily Mail. "And I never took offense. I mean I was flashed, humped, bumped, grabbed. I think he probably did it to a lot of people...but it was so much fun." The book also reveals that Williams once "goosed" an elderly actress playing his mother by putting a cane between her buttocks.
