Spiking this concoction is the palpable chemistry between Ted Danson's Sam and Shelley Long's Diane Chambers, fledgling waitress and self-described "student of life." The battle lines are drawn in the episode "Sam's Women": He's the "dim ex-baseball player" and she, "the post graduate." But, as Carla so indelicately puts it, they can't "put their glands on hold." In the first blush of lust, they were primetime's most potent mismatched couple until Moonlighting's David and Maddie bantered entendres. Here are little remembered facts: Sam was initially "an astute judge of human character." Guest stars Fred Dryer ("Sam at Eleven") and Julia Duffy ("Any Friend of Diane's") were among those considered for the roles of Sam and Diane. A pre-"Night Court" Harry Anderson stole his scenes in his recurring role as flim-flam man Harry ("Pick a Con...Any Con"). The lack of a commentary track is a disappointment, as are the extras that wouldn't fill a shot glass. Still, Cheers patrons can expect plenty of happy hours with this set. --Donald Liebenson
