Friends opens its seventh season with two prime episodes, originally telecast back-to-back. In the premiere episode, Monica (Courteney Cox) is dancing on air after announcing her engagement to Chandler (Matthew Perry). But just as she is planning a champagne party to celebrate the occasion, Monica is taken aback at the spectacle of her brother, Ross (David Schwimmer), in the arms of Rachel (Jennifer Aniston) -- a coupling that was supposed to have been over and done with during the previous season. Convinced that Rachel is trying to "steal her thunder," Monica goes ballistic -- while Chandler begins to wonder if getting married is such a hot idea after all. ~ Rovi
