Through Babelfish:

The quick brown fox jumps over the lazy dog.

English to Dutch:
De snelle bruine vos springt over de luie hond.

Dutch to French:
Le bruine renard rapide saute au sujet du chien paresseux.

French to Greek:
Bruine αλεπού γρήγορη αλλαγή σχετικά με το οκνηρό σκυλί.
(Note lack of translation of "Bruine")

Greek to English:
Bruine fox fast change with regard to the okniro' dog.
(...And we lose the "lazy" -- and somehow "jumps" has become "change with regard to")
