Because I would really like to make this story popular, and FanFiction has no one posting or reading Thursday Next stories, I'm plugging myself!
So go read my story! It's a crossover of the Thursday Next Novels and Doctor Who, such as the one Jasper Fforde so ingeniously mentions in "One of Our Thursday's Is Missing". And yes, some of the grammar is bad. Feel free to correct me, just don't be an ass about it. So...Without further ado...
Here it is! http://www.fanfiction.net/s/9073326/1/Thursday-Next-A-Man-and-his-Box
Read, review, retweet!
