My idea(s) for the final Seinfeld:
-The entire series run was actually a figment of Kramer's imagination, who is actually an autistic savant living with his parents (Pat Paulsen and Ann Meara).
-George finds that he is being stalked by a one-armed man named Art Vandelay (Robert Vaughan) who is enraged with George for using his good name in the pursuit of various half-baked schemes. A tense final showdown takes place in an abandoned amusement park between George, Vandelay and the ghost of Vince Lombardi (Jerry Stiller).
-Jerry meets up with Monica, Rachel and Phoebe from "Friends." He can't decide which one to date, so he and George hatch a scheme in which Jerry would suggest an evening of group sex to the girls. Plans go awry when the girls out themselves as lesbians and move in with Elaine.
-Elaine upsets Jerry's parents with her claims that the Holocaust never happpened. Newman is aghast when he spies Jerry and Dolores feeling each other up in a movie theatre during "The Sorrow and The Pity."
-Kramer goes up on the space shuttle and joins Mike, Crow and Tom Servo on the Satellite of Love where they will spend eternity lampooning episodes of "The Single Guy" and "Caroline in the City."
What do you think, sirs?
