One incredibly discerning Sorkin viewer named Kevin Porter has assembled an intricate look at the phrases and conversations that come up over and over again in Sorkin's writing.
Some of them are relatively minor. In a body of work as extensive as Sorkin's, it's not too unbelievable that many characters would say "You think?" or "You bet!" - but some really good lines noticeably come up again and again and again. His self-plagiarism has been common knowledge among Sorkin's devotees for a while now, but this comprehensive, already-viral supercut makes a damning case. The next time a studio buys a new Sorkin script, they'll probably want to stipulate that it's 100% original.
