The Encyclopedia of Guilty Pleasures:1,001 Things You Hate to Love by Sam Stall, Lou Harry and Julia Spalding, 320 pages

I came across this book showcasing horribly fun and awful things we love but shouldn't. It ranges from genres to people, shows and fads. Each entry has historical data, illustrations, and cross referencing, so if you want to know about meatloaf (both the dish and the singer) this is the book for you.
