Now I'm pissed

So I'm reading SICP, like always, every day. I'm finished for to-day, and, just before closing the book, I take a quick sniff. All's cool, until I realise something horrible -- there's a red smudge on my book. After quick consultation with my mirror, I conclude that my nose is bleeding. Mother-fuck, now page 149 of my SICP has a horrible red-brown linear stain all over it.

Put a small amount of bleach on the stain and leave it for the evening, with the book open. The stain will have faded to almost nothing when you return in the morning.
