Are you bringing back the Spontaneous Generation?! That's great! Well here, I have a post to start it off.

This is a band called Flight of the Conchords. They are self-described as "New Zealand's fourth most popular guitar-based digi-bongo a cappella-rap-funk-comedy folk duo". As of now, you can only see their work from HBO's One Night Stand on YouTube. Be sure to check out Business Time, Jenny, and the Gansta Folk Battle between the Rhymenoceros and the Hiphopopotamus.
