When you watch season 9 you fully understand that Jerry Seinfeld's heart just wasn't into the show anymore. After Larry David left Seinfeld had to try to run the show on his own and season 8 reflects his uncertainty with a lot of hit and misses where he's trying to find his voice, Seinfeld has commented how he wasn't sure he could even do the show without Larry, when you get to season 9 you can tell it just ran its course with him and he wasn't interested anymore. This clip show episode is evidence of that, rather than write two episodes for the season they mailed it in with a clip show, something that would never happen today because fans would go insane.
