It's sure to be a night of ladies behaving badly: Showtime's Nurse Jackie and The United States of Tara are back tonight for their respective second season premieres. Jackie Peyton, R.N. will deal with the fact she learned at the end of last season - that her husband has become friends with the guy she's seeing on the side. Oof. What I'm looking forward to most, though, is Peter Facinelli as the arrogant Doctor Cooper.
