well to be fair space marines aren't a light-hearted bunch. bio-engineered, psycho and hypno-indoctrinated to be efficient killing machines and a life of battle doesn't leave much time for them to be cracking knock-knock jokes :)

i haven't read that much 40k novels but they've all been space marine oriented, and while there is the occasional character who has a sense of humour i find any general humour to be from situations rather than dialogue.
