Actor Jason Alexander who played George Costanza in “Seinfeld” turns 53  today. I am sure over the years I’ve seen every episode of Seinfeld. I do not believe it is THE comedy of all times. It was alright. I do think that the key character in the entire show was that of George Costanza. The George Constanza character was based on Seinfeld co-creator Larry David. Without George the show wouldn’t have worked.
