I once had a record of Mozart's comic songs, put out by Deutsche Gramophon Gesellschaft. Some of the "translation" was less than exemplary. For example:

The record included a song called "Das Bandel." In English, "The little Ribbon." The song was about a young man who was teasing his wife, who was desperately looking for her lost hair ribbon. After carrying on for an appropriate length of time, the man finally says "Look -- Ich hab's im Handel!" meaning "Here it is -- I have it in my little Hand.

But instead of translating "Handel" as a diminutive of "Hand," the translator wrote "Look, I have it in my trade!"
