As a matter of fact, everything here (with all the frantically-eclectic running around) are just kinda there... even and especially Seinfeld himself, doing his best to make every... single... second.... matter...
For either an intended slapdash laugh, or perhaps to cover up the fact that, as a novice director, he's bought into the old con-man's adage that...
