I had a friend who interned at the Roundabout in NY for a season and when he came back he was the biggest name dropper. SJP and Matthew Broderick were two of the many, many people he had drinks with (according to him). I finally asked him when he was going to get over this stage!
Also, I forgot to mention I met Salman Rushdie... I helped run a book signing he did at Wash U.
