My only complaint/critique of Mr. Hollywood's recent publication is his use of the he age old tactic of pumping up the lead. By comparison this lead is relatively in it treatment of the truth. It certainly will not cause embarrassment to Mr. Seinfeld.
Regardless, as someone who disseminates information to the general populace there is no room for speculation.

I challenge you to provide any evidence that Mr Seinfeld's earliest intentions involved acting on stage and screen. He was a rising star in the stand up field from early on and was gaining the attention of people who eventually partnered with him

So, factually he was let go as an extra, but that happens daily and in no way did that event push him towards becoming one of the best comedians of our time.

I find it hard to believe that the same people describe him as a douche. That would involve knowing the person. The argument that Jerry had to surround himself with beautiful actresses on certain episodes is more a function of the people who pay for the entertainment you watch.

It's cross promotion. These actors and actresses have also been noticed by the studio executives and that's how it works. They must be seen and you do that by placing them on a number one show

Millionaire Jerry could have had a woman for every Porsche he owns but that's only skin deep
