5. "Anytime you want to include me... 'No, I'm Sherlock Holmes. I always work alone because no one else can compete with my massive intellect!'" - Watson
In the episode The Blind Banker, Watson delivers this line that pretty much sums up Sherlock. He's a brilliant mind who is in fact so brilliant that others working with him seem like idiots sometimes. Also, the fact that Watson really wants to always help Sherlock is great and the reason why they are such a lovely duo. The entire episode is about Sherlock and Watson investigating a series of ciphers representing numbers in an ancient Chinese numeral system which have been left by a Chinese smuggling ring hoping to retrieve an item they stole. The quote is important within this plot - by uttering 'I'm Sherlock Holmes,' Watson inadvertently makes himself out to be the World's Greatest Detective, and draws the attention of the murderous gang.
