Oy vey. Or as Virginia Chance (Martha Plimpton) might mangle her Hebrew-isms: "Molotov! (for mazel tov)." Fox sure doesn't make it easy to say goodbye to Raising Hope as it ends its third season on a new night with back-to-back episodes (9/8c), the sort of treatment you'd normally see from a network burning off a show in which it has lost faith. Thankfully, that's not the case here. Hope has already been picked up for a fourth season, and it goes out on a delightfully deranged musical high, with Burt (the sublime Garret Dillahunt) center stage as he frantically preps for his overdue Bar Mitzvah.
