I know I did that a good bit when i was a kid. I remember reading Gone with the Wind back to back in high school, and The Westing Game when I was a bit younger. I've also done it with series; I know i read the first four books of Anne Rice's vampire series then read them all again. More recently, I listened to The Lord of the Rings a couple years ago then relistened immediately. I don't do it too much anymore as there are so many books I want to read!
also, Happy Birthday to a great guy who will always be my little brother, though now he's 31, married with 3 kids!
