Hmm, let's see. At thirteen I was really obsessed with The Breakfast Club and pretty much any other John Hughes movie (despite the fact that this was only five years ago), so I think I would have gotten the "Dear Mr. Vernon" speech tattooed on me somewhere. You know, I was really into Rocky Horror Picture Show at that time too.
Let There Be Lips!
Oh, and I was obsessed with the phrase "Everything Dies" with like little dead flowers around it. That would have been a lovely contribution to my body.
