This is certainly one of the finest episodes of the Conchords. Michel Gondry takes a turn at directing the show and his presence is certainly felt.
The songs are superb, the videos are hilarious (especially the 'ex-girlfriend' segment - it really is soo Gondry and wonderful!) and the plot is good. While I've not been too sure about the second season of the show, 'Unnatural Love' certainly made me see that there's still life in it! 9/10
P.S. And I couldn't help but laugh at the Australian stuff with my Aussie girlfriend...so bloody true!
