I saw Shrek the Third yesterday and must say I was disappointed by its lack of inventiveness and plot. The first two movies were quite good, but the team seems to be running out of ideas.
This leads me to the point of this post, funny fairy stories. The best comedy book based on fairy stories would have to be The Princess Bride by William Goldman.
Famously made into a very funny and successful movie, Goldman's book takes a lot of the tropes of fairy tales and weaves them into a story all his own. With memorable characters and jokes Goldman's book is fun to read, or read aloud, it is guaranteed to put a smile on your face.
So instead of going to see a film that is only funny in places, borrow The Princess Bride and enjoy a really funny book. Trust me you will not be disappointed.
