The funniest things I've ever read, however, are the Molesworth books themselves, and if you've never read The Compleet Molesworth, then you should do so immediately. There are very few things which could reduce me to tears of laughter when I was nine and which can have exactly the same effect on me nearly twenty years later, but that book is one of them. I must have read it a hundred times, and it never gets stale. In fact, I'm off to re-read it now...
*Note: the readings of the books in this show can't achieve the same effect as the written version, not least because the reader was a rather whiny small boy, so don't let that put you off.
