The idea of someone changing your position on his or her speed-dial based on your relationship with them had some promise, but they just didn't do enough. Say, Jerry's girlfriend changes the speed dial but forgets to change the labels. Jerry tries checking his answering machine, but when he pushes the button with his name on it, he gets Newman or Bania or Crazy Joe Davola or one of her ex-boyfriends. That would have been a lot funnier. Jerry tries to figure out why they are on her speed dial, where his number went, who else is on it, etc. They could have had Jerry competing with the guy in the #1 spot a la George's competition with Chelsea Noble's boyfriend.
Then they had some kind of weird "Graduate" thing with Jerry and his girlfriend's mother. It just went nowhere. They've done enough parodies to know how to do it right. I don't know what they were thinking when wrote it like that.
Am I the only one who kept asking himself why George didn't just simply QUIT?? Why did he have to get fired, why couldn't he have quit? I couldn't get over that, so I didn't laugh at anything he did to get fired.
Elaine's clothing store thing. Again, it had some promise but went nowhere. See the last time a vendor refused to serve Elaine (The Soup Nazi) for how it's done. Maybe if she had discovered the store uses child labor or she opened up her own store across the street...Maybe it would have worked. But they just didn't even try to do anything funny with it.
