I was thinking about what the show would be like without his quips and advice, and then I remembered a book I'd seen back on Amazon.com a while ago—Bobby Singer's Guide to Hunting by David Reed. Curiosity got the best of me and I checked it out.
The book is written from Bobby's perspective, and in his unmistakable voice. I could totally hear him speaking the words as I read. His typical redneck tone alone makes it a fun read.
I don't want to give too much away, but the gist of the book is that Singer is losing his memory and has 24 hours to pen instructions to pass along to Dean and Sam. Among the contents of the book are chapters not only about the monsters, demons and other eerie creatures that hunters can expect to encounter, but also more in-depth looks at important people in Bobby's life as well as the man himself.
It's an awesome read for every Supernatural fan, especially those who have soft spots for Bobby Singer. One of the things that keeps the show's fanbase so loyal is the relationship they have with the main characters. I haven't read many of the other Supernatural books, but Bobby Singer's Guide to Hunting definitely delivers the genuine, personal flavor of the show.
Incidentally, I found it interesting that this book was released in September, and now, well, we're not so sure the Winchesters will be seeing ol' Bobby again. Foreshadowing? Arguable.
