That is fun, but it proves an important thing, unless you understand the two languages and using it to save some time (after all probably something like 80% will be usable) yu should not translate on line anything important. Even small mistakes can become important and help turn something around (it can also make you look like a fool.)

several years ago a co-worker that worked in the US moved here, his name was Chew and responding to a guy (who is francophone) decided since he was in Canada now he would respond in French. He wrote the e-mail, translated and then asked someone for a confirmation on the translation. The funny thing was that the translator saw "chew" and translated it to mastication and tried to make the sentence make sense with that.
