From "Whitechapel: Episode #1.1"
You're a Ripperologist, aren't ya?
Why, yes, I am, and I also host an excellent Ripper tour. A lot of the operators use their tours to promote very inaccurate theories, but I pride myself on my strict adherence to the known facts.
Well, there's a fact... you're a loser. Now get out before I nick you for wasting police time.
