Molly (Melissa George): Emma's hot nanny, whom Ross gets to hire since Rachel does not see it in her. When Joey sees her, his lady killer instinct kicks in. Ross tries to make Joey stay away from her when he flirts with her, which makes Joey want her more. Ross wants Chandler to watch Joey and make sure he does not go after Molly. When Ross is lecturing Joey there is a knock on the door and it is Molly's girlfriend. They kiss, and Ross no longer has a problem—although Joey's even more turned on by her lesbian status. Molly makes one more cameo appearance, in "The One Where Monica Sings" (airdate January 30, 2003; Season 9, No. 13).
