WTF!!! How does it translate "The cat's tail" to "Timothy". Any explanations?

Google translation gives the same result - http://translate.google.com
Alta Vista Bablefish http://babelfish.altavista.com translates "The cat's tail" to "La queue du chat" but also translates "La fléole des prés" back to "Timothy". Weird.
