Mark Twain received this letter from a Danish customs officer in 1879:
Please to excuse that I fall with the door in the house, without first to begin with the usual long ribble-row. I want to become the autograph of the over alle the world well known Mark Twain, whose narratives so apt have procured me a laughter.
If you will answer this letter, I will be very glad. Answer me what you will; but two words. If you will not answer me other so write only, that you do not like to write autographs.
It’s not known whether he responded, but on the envelope Twain wrote, “Please preserve this remarkable letter.” See Lost in Translation.
