You need a place where everybody knows your name – even if it's just a dive bar in Boston full of regulars with no place else to go. Cheers started with a focus on the mismatched romantic banter between Ted Danson's washed-up Red Sox pitcher Sam and Shelley Long's uptight bookworm Diane. ("Over my dead body!" "Hey, don't bring last night into this.") But it regularly renewed itself by bringing in new blood like Woody Harrelson, Kirstie Alley and Kelsey Grammer. Cheers was like that bar, to the point where you could tune in just to see which regulars would hang with you tonight.
