Mine has to be the "Marine Biologist" episode, where among other things:
Kramer uses the Atlantic Ocean as his personal driving range;
Jerry convinces Elaine that the true title for "War and Peace" was "War...What is it Good For?;
George poses as a marine biologist to his girlfriend (instead of the usual 'architect' ruse);
and Carol Kane is clocked in the head...twice...by a renegade electronic personal organizer and a broken tape recorder.
I can just hear it now: "The sea was angry that day, my friends. Like an old man trying to send back soup in a deli."
God, I miss that show.
