Looking it up, Happy Days lasted 11 season, but Richie was gone for the final few. Not sure what other shows might have matched or beaten that. MASH lasted 11 seasons while the Korean War got cancelled by the studios after 4. But that had adult actors so the aging didnít really matter.
At least not in a family setting.
About as much as people suggested was Erica/Geoff getting hitched and having a baby. But you'd be going waaaay off the track of the reality of Adam's life in that case.
Oh well. Already in their eighth (!) season. Can't keep going too much longer with " On March 24th, 1980-something ".
