Perhaps you're beginning to wonder if this little "Joseph" character I write about is entirely exaggerated for the sake of a good laugh. Really, he's not. He's that funny, and that incorrigible. (If you don't know what I'm talking about, see here, here, here, here and here.) The latest? I offered him some lemonade at lunch, and he declined. "Why?" I asked him. "Because," he replied, "lemonade makes me nervous."
