I remember there being a link to this on the other site, but I don't know if it's ever been posted here. It's like the childrens' game of "gossip" or "telephone" (and another graphic illustration as to why relying on machine translation for your tattoo might not be a good thing!)

Start with a phrase in English and see what happens after the translator goes back and forth between English and Japanese. I started with "None but God may judge me" (one of our all-time favorite tattoo requests) and ended up with "God is there in every potential decision."
