I've seen it, and didn't think it was offensive. I also wouldn't think it offensive if it was three men oggling a woman. Sexual politics have thankfully moved on over the last thirty or so years. Both sexes can be seen as predatory, which they can be, and it is tongue in cheek.
What I do think is sexist is Sheila's Wheels car insurance. That discriminates against men, and there would be an outcry if male only insurance was offered. I don't know how they manage to get away with it lawfully...besides the theme tune drives me mad.
