As you may or may not be aware, we're rather taken with the idea that the worlds represented to us in TV and film are actually real. It's an idea that's brought us some trouble in the past. Like that time we kept trying to walk through that passage from Goodnight Sweetheart (Duckett's Passage in East London, if you want to give it a go).
Thanks to Black Books, we were under the assumption that all bookshops would be full of quirky characters and randomly funny situations but after spending about three Saturdays in a row in Waterstone's, it's sadly not the case.
If you'd rather continue living in the blissful ignorance that Black Books is real then we have a devlishly tough quiz for you. Based on that documentary you love, yeah?
You can watch all episodes here.
