The "Spoilt" Threadless shirt, by Oliver Moss, has more spoilers than you can shake a stick at. I laughed out loud. Link (Thanks, Fipi Lele!)
Update: Harold sez, "The webcomic Theater Hopper has been selling t-shirts like the Threadless tee for quite some time now. The artist even has two different editions."
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
