Just thinking, Discussion has said that the original plan for Kramer was: Hoffman, then they used: Kessler, then they got the rights to use: Kramer. All these names are Germanic names. Any reason for that? Just wondering.
Now, I know from comedy experts that words and names with a *K* in them are generally funny so the Kramer/Kessler is well founded that way.
BTW: In Get Smart (my second favourite series :-) ) one arch enemy is also Kessler.
