Books which made me laugh out loud

On these long cold dark days, when the sun comes up after you leave home and goes down before you leave work, you need something cheering, and I can’t possibly let you down when you look at me like that, so I decided to make a list of the funniest books I knew.  And as I started to list them, I realised that the books which make me laugh, or in some cases smile (but smile a lot) are almost all (with one obvious, though slight,  exception) the stories of middle-class suburban men failing slightly.  I wonder what that means?

I’m sure there must be more which I can’t think of offhand.  I’ll post them as I do.
