This cracks me up. If I gave graffiti a go, my result would probably look a lot like Edward's.
Last night I went to see a local show at The Hideout, a name-appropriate dive bar/music venue in town. I noticed that they redecorated the bathroom recently with odd stickers in different geometric shapes in seventies shades of peach, brown and yellow. Someone did not approve. Hovering eye level across from the commode was someone's judgmental scribble: "This is the ugliest bathroom I've ever seen." Below that, a devoted patron angrily responded: "Fuck you. I like it."
