HAPPY ENDINGS - "Party of Six" - So many bad things have happened every time the friends celebrate Penny's birthday, they're wondering if her special day might be cursed. They set out to find a restaurant where they can celebrate, where one of them hasn't been banned or where someone won't run into an ex -- something that's almost impossible -- on "Happy Endings," WEDNESDAY, MARCH 14 (9:31-10:00 p.m., ET) on the ABC Television Network.
