Customer: Excuse me, do you have any signed copies of Shakespeare plays?
Bookseller: Er…do you mean signed by the people who performed the play?
Customer: No, I mean signed by William Shakespeare.
Customer: Did Charles Dickens ever write anything fun?
Customer: I read a book in the sixties. I don’t remember the author, or the title. But it was green, and it made me laugh. Do you know which one I mean?
Customer: I’ve forgotten my glasses, could you read the beginning of this book to me to see if I like it?
