This TV show really avoided the popularity it deserves. If more people watched it, it would have gained the cult following that Little Britain or IT Crowd have. It consisted of little known actors at the time: Dylan Moran (now a stand up comedian!), Tasmin Greig (Green Wing, Shaun of the Dead) and Bill Bailey who was actually in a few things before hand, but hes much bigger now doing Stand up tours across britain.
The show was about a bad tempered Irish book keeper, and the day to day adventures you could only expect in a book shop! The standard of comedy in this is so high because the writer was a writer for Father Ted and the IT Crowd as well. If you're british you can watch all of the episodes here:
I really recommend it, you won't be disappointed!
