QUESTIONS I HAVE WATCHING SEINFELD FOR THE FIRST TIME

To be updated as the series progresses...
  1. How does Kramer afford to live alone in a nice building on the UWS?
  2. Do the writers know no one in NYC in this socioeconomic background have cars/use them as often as these characters do.
  3. How do they never have trouble finding a parking spot?
  4. Did Elaine get her hairstyle from fundamentalist Mormon prairie women, or did fundamentalist Mormon prairie women get their hairstyle from Elaine?
  5. Jerry claims he has never seen a single episode of I Love Lucy, yet in the very next episode, during a standup bit, he references Fred Mertz. How did no one catch this?
