Though just A Little Digging leads me to believe this is just spam This Screen Shot I found over on Digg a few weeks ao from a message board someplace cracks me up:
I was just thinking.... My sister does -a lot- of reading and spends roughly $1000 a year on just books alone. Most of them she reads once then never looks at again. Is there any kind of like... video rental store but for books? Would make things a lot cheaper, plus once one person has read one the next person can get enjoyment from it etc.
