This was definately the funniest episode for a good while. No-one seems to have mentioned the honeymoon diary, the last entry made me laugh out loud. I think the less weepy episodes tend to be more informative, the subject spends less time emoting and more time asking questions ( with the possible exception of Graham Norton- who I am a fan of but who really didn't seem to fully engage in the search).
By the way, in case any of you have forgotten or didn't know, you can view extra footage from the show via the WDYTYA magazine website.
