Edward Lear once overheard a man maintain that his Book Of Nonsense was written by someone else. This is how he responded:
Says I, joining spontaneous in the conversation — ‘That is quite a mistake: I have reason to know that Edward Lear the painter and author wrote and illustrated the whole book.’ ‘And I,’ says the Gentleman, says he, — ‘have good reason to know, Sir, that you are wholly mistaken. There is no such person as Edward Lear.’ ‘But,’ says I, ‘there is — and I am the man — I wrote the book!’ Whereupon all the party burst out laughing and evidently thought me mad or telling fibs. So I took off my hat and showed it, with Edward Lear and the address in large letters — also one of my cards, and a marked handkerchief: on which amazement devoured those benighted individuals and I left them to gnash their teeth in trouble and tumult.
