This A/B-list actress and comedienne rarely if never talked about her teen years to interviewers.
When she was growing up in New York City, and still very much underage, drunken friends of her father (who was a bouncer at several mob-controlled saloons) would rape her.
One man gave her an STD.
Considering her public persona, it was something that was too painful to discuss.
