When I worked for a publisher in London, part of my job involved sending promotional material to a distributor of ours in Dubai. So one day I carefully made up a package of fliers and decided to go the extra yard by using a web-based translator to write the message; "Delicate, Do Not Bend" in Arabic on the front of the envelope - and off the package went in the mail.
So I called them up the next week to ensure it had arrived safely and they confirmed its' receipt - with a chuckle...
"Why are you laughing", I asked.
To which my contact replied:
"Hahahaha. Because when the package arrived, it had "NO TRANSLATION FOUND" in big letters on the front. Thanks for giving the office a laugh."
