They are hired by Oscar to help with his new company, "Dirtballs", and to spread dirt all over the street. But, each person they give dirt to finds an alternate use for it (instead of using it to get dirty). Hiram and Burt are amazed at what dirt can do and sing a song about dirt. Oscar gets fed up and shuts down the business. Now out of a job, the two decide to go into musical theater and shuffle off singing "Give My Regards to Broadway."
The two are caricatures of Bret McKenzie and Jemaine Clement, the singing duo on the TV series Flight of the Conchords. Hiram is made from an Orange Gold Live-Hand pattern and Burt is made from a Pumpkin Live-Hand puppet.
