Pies and Prejudice: In Search of the North by Stuart Maconie. I don't often say this (because it drives me mad when I see it on book jackets) but it did "make me laugh out loud"
In fact I was weeping with laughter at such gems as this reference to annoyingly cheery cockernees "people in the North are perceived as dour because their fishmongers don't dress in rhinestones and hold parades" and "as Dennis Waterman placed his thumbs in his lapels, I felt the blood drain from my face"
Maconie holds the honour of having written the book with the best title ever, in the shape of "Cider with Roadies", which is also one of the funniest books ever written IMHO.
Read it and weep.
