When I was a kid, there was this Bookmobile that would drive around our neighborhood about once a week or so, it was this big RV full of books from the public library. Once I got this book of jokes told by Fozzie, and then we moved and I never turned it in. To this day, whenever I run across that book in a box or something, I feel guilty and I hide it real quick in case the librarians are after me or something.
