It's tough not to respect TV shows which know when their numbers is up and decide to bow out at just the right time, before things start to get stale and the fanbase inevitably turns on them.
But considering the advertising and syndication dollars which can be made from even a terrible season of a hit TV series, it's little surprise that many shows end up dragging themselves to the finish line.
While none of these 10 TV series went egregiously past their expiration dates, each nevertheless had a ripe dramatic opportunity to wrap things up the year before, but cynically milked things for one extra season.
Though some fans may well defend these seasons as entertaining in spite of their excessiveness, it's clear that each show would've maintained a far greater sense of integrity had it resisted the urge to take one final dip into the cookie jar.
And if you take anything at all away from this list, it should surely be that NBC has no shame when it comes to flogging its sitcom shows to within an each of their life...
