9. "I'm Not A Psychopath, Anderson, I'm A High-Functioning Sociopath. Do Your Research." - Sherlock
This is still in the first episode and it's probably the most quoted quote from the show. It's incredibly hilarious how much Sherlock gets on Anderson's case and when he said this quote it made us realize just how great Sherlock is. To retrieve the suitcase, there's a pretend drugs bust at Sherlock's house and they find the suitcase and Anderson throws out the quote "We found the case! According to someone, "the murderer has the case. And we found it in the hands of our favourite psychopath!" Anderson seems so excited at the prospect of Sherlock being the murderer, and it's very funny how he gets shut down.
