Friends continues its hit-and-miss history with A-list cameos. Robin Williams and Billy Crystal ("The One with the Ultimate Fighting Champion") are about as funny as the woeful film they were hyping, Fathers' Day. More memorable is Isabella Rossellini ("The One with Frank Jr."), whom the hapless Ross meets just after crossing her off his "freebie list" of celebrities Rachel would allow him to sleep with. Other classic episodes include the season-opener, "The One with the Princess Leia Fantasy" and "The One with the Flashback," which offers some provocative near-couplings between Monica and Joey, Ross and Phoebe, and Chandler and Rachel. Add a chick and a duck ("The One with a Chick, and a Duck"), and you have a benchmark season in this irreplaceable series. But still: You'd think a million dollars an episode would buy some DVD cast commentary! --Donald Liebenson
