Well that would be one way to make sure you did actually get the right guy.
Unless he’s not one of the five.
Sherman, I don't know why you have decided that making sure it's the right guy wouldn't be a priority for me if I ever decided to undertake vigilantism, but allow me to take this moment to reassure you that if I ever do decide to hike up my dress and kick in someone's door, I will remember your words of wisdom and pause and ask myself, "Is this the right guy?" before I swing my M14 around and go postal.
I hope you will be content with knowing that you have enlightened someone today. In fact, the next time I am faced with any dilemma, I will stop and ask myself the most obvious question I can possibly think of in your honor (re: Toaster doesn't work. Is it plugged in?)
