"I'm afraid John, I can't congratulate you. All emotions and, in particular, love, stand opposed to the pure cold reason I hold above all things. A wedding is, in my considered opinion, nothing short of a celebration of all that is false and specious and irrational and sentimental in this ailing and morally compromised world. Today we honor the death watch people, that is the doom of our society and, in time one feels certain, our entire species. If I burden myself with a little help mate during my adventures it is not out of sentiment or caprice, it is that he has many fine qualities of his own that he has overlooked in his obsession with me. Indeed any reputation I have for mental acuity and sharpness comes in truth from the extraordinary contrast John so selflessly provides. It is a fact I believe brides tend to favor exceptionally plain bridesmaids for their big day. There is a certain analogy there I feel. And contrast is, after all, God's own plan to enhance the beauty of his creation. Or it would be if God were not a ludicrous fantasy designed to provide a career opportunity for the family idiot. The point I'm trying to make is that I am the most unpleasant, rude, ignorant and all-round obnoxious arsehole that anyone could possibly have the misfortune to meet. I am dismissive of the virtuous, [He looks at the priest], unaware of the beautiful [He looks at the maid of honour] and uncomprehending in the face of the happy [He looks at Watson and Mary]. So if I didn't understand I was being asked to be best man, it is because I never expected to be anybody's best friend. And certainly not the best friend of the bravest and kindest and wisest human being I have ever had the good fortune of knowing.

John, I am a ridiculous man, redeemed only by the warmth and constancy of your friendship. But, as I am apparently you best friend, I cannot congratulate you on your choice of companion. Actually, now I can. Mary, when I say you deserve this man, it is the highest compliment of which I am capable. John, you have endured war and injury and tragic loss - so sorry again about that last one - so know this; today you sit between the woman you have made your wife and the man you have saved. In short, the two people who love you most in all this world. And I know I speak for Mary as well when I say we will never let you down and we have a lifetime ahead to prove that."
