I listened to this on audio, and I dug the narrator. I dug him a lot!
This book was funny and fun. A lot of the humor was laugh out loud funny and a lot of the fun was in spotting the real folk amidst all the fictional characters.
I had a blast listening to this and if I could afford it, I would listen to the entire Discworld series narrated by Mr. Briggs. Alas, I cannot, so I guess I still have to read them.
