Best Marilyn Monroe performance?

[nomis]

...I believe there was maybe a couple of one night stands with JFK.But it was Robert she really fell for..Micheal Selsesman,who is still alive and did her publicity with Jacobs and Newcomb tells some very interesting stories of that fateful summer I wish he would do a book..the 1985 documentary "Say Goodbye To The President" is fascinating..either Robert was in LA that Saturday or all those witnesses are lying...what a cast of characters Greene,Murray,Lawford,Newcomb and the rest are....
