I do not know who Lena Dunham is. Seriously I have no idea. I hear her referred to but do not know who she is. (don’t care or want to either)
She produced and starred in a show on HBO titled Girls, which might have drawn one-half million viewers for an episode (no one knows as HBO won't disclose such numbers). I believe it ran for a couple of seasons.
Later, she got her autobiography published where she freely described sexually abusing her younger sister (I am not kidding) and made up a tale about being raped while at college at Oberlin.
