What was the last novel to make you LOL, out loud?

I'm a big fan of novels which make me laugh. It could be something that happens in the story, like the excellent funeral scene in Neil Gaiman's, Anansi Boys, (if you get a chance, I thoroughly recommend the audio version, narrated by British comedian, Lenny Henry).
 
It could be something a character says. Terry Pratchett writes some hilarious dialogue for his characters. I think he's especially good at having people misunderstand another person's words with amusing results eg: In Wyrd Sisters, when Nanny Ogg sniggers at the word 'thespian' which causes Granny Weatherwax to declare in a condescending tone that Ogg 'doesn't even know where Thespia is.'  

The Goblin novels by Jim C. Hines (jimhines ) contain a great balance of narrative and dialogue humor. I particularly enjoyed the Goblin sayings beneath each chapter heading in the second book. 

The last 'book' to make me laugh out loud the audio version of Harry Potter and the Half-Blood Prince. Professor Dumbledore's subtle brand of sarcasm often goes unnoticed by the people he's talking to, especially when those people are the Dursleys.


How about you?
