I confess that 'Going Postal' was never one of my favourite of the Discworld novels but re-reading it for the first time (I think) since I first bought it revealed some nice bits of Pratchett humour which I'd forgotten. The passing references to the gods particularly amused me. I'm still not convinced that Moist von Lipwig is one of his best heroes but I do have 'Making Money' to hand, which also features him, so I'll give that a go and see if Terry can convince me.
