The really significant difference is that there's no Florence Henderson on Friends. The kids have the run of the house now. Greg and Marcia (make that Ross and Rachel) can neck 'til they're black-and-blue from chin to chest. What happens without a stern-but-sensitive Brady lecture to slap one's ass into gear, California-style? Well--nothing happens. Finally voicing what viewers at home have long wondered, Phoebe's long-lost brother asks the assembled Friends, "How do you guys get anything done?", as they sip their youth away on Central Perk's central couch. Chandler answers: "We don't."
