Misunderstood Kanji characters
This is an article in the Chicago Tribune that shows random tattoos found on Chicagoans of Japanese characters, comparing what they think that tattoos mean, and what they actually mean. Awesome.

This one is my favorite:
What he thinks his tattoos say: "Love hurts."
What they actually say: The meanings of the two tattoos roughly translate to "love" and "it hurts." They'd never be used together, however, and they appear to say "love -- OW!" or "I love this tattoo but it was painful to get."
