It shows the two main characters in their alter egos as the Hiphopopotamus and the Rhymenoceros. Basically, two white guys trying their hand at Hip-Hop, and failing miserably. Then again, they’re meant to.
Some of the lyrics in this song are much cleverer than what you’d find in a real Hip-Hop song by Snoop Dogg or P. Diddy and the like, but they’re also a but wussy. “Motherflipping” being a case in point.
They’re also extremely funny, as is the style the whole thing is delivered in. It seems there isn’t a genre that Flight Of The Conchords can’t successfully rip the piss out of.
