I think the main purpose of the last scene (perhaps, the first) of the 11/20 episode was not to show Jerry's first meeting with Kramer per se, but to correct one of the biggest inconsistencies of the show, the fact that Kramer was originally known as Kessler...
I think the writers were thinking of those of us who study and dissect every little bit of the show when they threw that idea into the script (in a very discrete manner, by the way)
I believe those two seconds in which Kramer corrected Jerry made the whole 30-minute show worth watching... what do you people think?
