After watching the season finale I noticed...
The doctor who delivered the message to George about
Susan's death was the same doctor in "The Junior Mints"
who allowed Kramer to observe his operation on the
fat artist.
Carol Leifer, who is also one of the writers for "Seinfeld"
and was in an earlier episode "The Kiss Hello" was one
of the bankers who went to greet Kramer with something
other than "hello".
The guy who said "Hey" instead of hello was the same guy who was taking tickects in last night's syndicated episode "The Movie"
According to my information...
132."The Invitations" Janeane Garofalo [ Jeannie Steinman ], Heidi Swedberg [ Susan Ross ], Stephen Root [ Mr. Lager ], Victor Raider-Wexler [ Doctor ], John Riggi [ Teller ], Sue Goodman [ Clerk ], Julie Clark [ Waitress ], Fred Goehner [ Delivery Guy ]
These are the credits from...

Maybe they just look similar...
