There's a program people called Bablefish, named after the Bable fish from the book, The Hitchhiker's guide to the galaxy which itsself is named after the tower of Bable.

In the book you stick the fish in your ear and then it translates all languages instamagically so that you can talk to anybody as you tour the galaxy.

Bablefish the program will attempt to translate languages for you. You can either type some text in or you can tell it a webpage and it will present that page translated for you.

Well, somebody in their spare time decided it would be fun to see what it would do if for example you translated from English to German then back to English then to Italian then back to English etc.etc. Check it out here.

Here's my test. Sorry about the bad words. It's just the first thing that came to mind.
