"A fellow told me one about Wembley yesterday," I said, to help on the cheery flow of conversation. "Stop me if you've heard it before. Chap goes up to deaf chap outside the exhibition and says, "Is this Wembley?" "Hey?" says deaf chap. "Is this Wembley?" says chap. "Hey?" says deaf chap. "Is this Wembley?" says chap. "No, Thursday," says deaf chap. Ha, ha, I mean, what?" The merry laughter froze on my lips. Sir Roderick sort of just waggled an eyebrow in my direction and I saw that it was back to the basket for Bertram. I never met a man who had such a knack of making a fellow feel like a waste-product."
