I was waiting for a ferry once, and there was a whole swarm of other cyclists waiting to get on. I spotted a tattoo on someone's leg with the Iron Man logo and some French. I kept watching and waiting for him to turn round so I could see the rest of it. I wasn't disappointed. "La vie est plus queue respirer." I suspect autocorrect was to blame.
I guy I use to work with was half russian and had some phrase tattooed across his arm. serbian cyrillic is different to russian, but a lot of the letters are the same so while I couldn't read all of it (let alone understand it) I noticed a few of the characters were mirrored. I don't think I ever ended up telling him though since it seemed to mean a lot to him.
