There are thousands of possible plotlines based on past plotlines for the final episode....George lands a job as an adviser to Guiliani, Elaine marries Perterman, Kramer sells his Tony, Nemman getting the coveted transfer to Hawaii, Babu returns to exact revenge on Jerry but is thwarted, Delores yells at Jerry. "My real name is Simon, you moron!", the Seinfelds and Costanzas senior reconcile only to start their feud anew, Kramer and Jackie Chiles take on Big Cable,
But I give you odds...that the final scene of the final episode will be the Four sitting at their booth in Monk's discussing such lively topics as: "Hey...how come people with athlete's foot look like they never played a sport in their lives?" or George lamenting his lack of success with women, or Kramer pitching a get rich scheme, or Elaine complaining about Puddy. I predict we will leave the gang just as we found them 9 seasons ago. This is also pretty much how every episode of this sitcom...and any other sitcom...has ended. Gang meets at usual spot...gang has adventure...life returns to normal at usual spot.
