Literary tattoos

I've edited newsletters, I've edited articles and reports. I've edited stories and poems.

But last week was the first time I ever edited a human body. 

To be fair, the tattoo was yet to be applied and I was only really being consulted on font size, but I noticed a grammatic error (it was a quote which had been cut down a bit, so the ends didn't quite fit together) and some dodgy punctuation. 

 
And, yes, it was one of my colleagues in the library - what have I been saying all along about librarians and dark underbellies (or in this case, two fairly symmetrical dark sides)?  You never know what lurks beneath the practical cardigan, stretch pants and sensible shoes. None of these pictures are of the tattoo in question, by the way.

It turns out literary tattoos are quite the thing. Not content with adorning their bodies with a rose/butterfly/names of soon-to-be-ex-lover/full-colour death metal scenario, today's bibliophiles, poet-fanciers and epigrammarians are wearing their favourite phrases, passages and even book covers close to their hearts...and other organs. 

I blame Robbie Williams.

It reminds me of the lines from The Rubaiyat of Omar Khayyam: 

The moving finger writes; and, having writ,
moves on nor all your Piety nor Wit
Shall lure it back to cancel half a Line,
Nor all your Tears wash out a Word of it.

More literary tattoos here: Huffington Post and here: Contrariwise and in the Guardian Books Blog but, for scale and variety check out the whole passages, illustrations etc at Yuppie Punk.

So you know what I'm going to ask, don't you?  What lines or phrase from a book or poem do you love so much that you would write them not in stone, but in your own skin?
