Hollow choc bunnies is brillaint one of the funnyest books about.

I'll throw into the mix Anasi Boys my Neil Gainman, it's like American gods with more jokes. Other books that aren't that funny but a jolly good read are 'We' by Zamyatin ( the book that heavy inspired 1984) and 'I am Legend' I forget the auther but it's a cool zampire book.
