Ah the Hitch Hiker's Guide to the Galaxy. I loved that and haven't reread it in a while, its about time. "They hung in the air the way that bricks don't" or something like that.

I tend to like gentle humour or black humour but find bullying humour offensive, or simply less funny. For instance I didn't find When Santa Runs out of Prozac terribly funny but I do like the song "Hey Santa where's my f**king bike!" quite funny.
