Right now I am on a bit of a BBC Radio sit-com kick.
Current favourite being Elvenquest. A low-grade fantasy author and his dog are abducted by an elven Lord, an armour-clad amazonian princess and a disgruntled dwarf and taken through a portal to a fantasy world (Lower Earth), because the dog is the prophesied 'chosen one' who will defeat Lord Darkness. Brilliant cast, including Stephen Mangan (from Extras).
Couldn't find much in the way of youtube clips but there's a sample on the audible.com site that gives a flavour of it.

and the one Youtube clip I was able to find, which has been dubbed over a clip of Disney's Hunchback of Notre Dame
