You're in for a treat because I've actually heard some of the story behind this tattoo. Legend has it that this girl came to a tattoo shop drunk one night and requested a tattoo that said, "I'm Gonna Kill You, Ray Romano," as in the famous actor/comedian, Ray Romano. The tattoo artist declined since she was clearly so drunk (you'd have to be drunk to want that tattoo), but told her that if she came back sober the next day, he would do it for free. As you can clearly see she came back the next day. That's HOW this tattoo came to be. As for WHY, I am uncertain.
I'm not sure what vendetta she has against Ray Romano, especially since I thought Everybody Loves Raymond. WHat happened to the good old days when you'd just send a death threat via the post?
