I Love this one quote from The Order of the Phoenix: (pg.65. of uk version)

"Some of them are working on recruiting more people to the Order-" Said Hermione.
"And some of them are standing guard over something" Said Ron" They're always talking about guard duty"
"Couldn't have been me, could it?" Said Harry sarcastically.
"Oh, Yeah" said Ron, With a look of Dawning comprehension... Harry snorted.


HAHA! Ron is hilarious! this was one of the funniest quotes ever, even though the book as a whole isn't as funny as the others, that one quote I think was the funniest over all, I can just imagine Ron acting like that!!
