One morning as Mark Twain returned from a neighborhood morning call, sans necktie, his wife met him at the door with the exclamation: "There, Sam, you have been over to the Stowes's again without a necktie! It's really disgraceful the way you neglect your dress!"
Her husband said nothing, but went up to his room.
A few minutes later his neighbor - Mrs. S. - was summoned to the door by a messenger, who presented her with a small box neatly done up. She opened it and found a black silk necktie, accompanied by the following note: "Here is a necktie. Take it out and look at it. I think I stayed half an hour this morning. At the end of that time will you kindly return it, as it is the only one I have? - Mark Twain."
