The Rock Jam skit was based off of the problem with the peripherals to the video game Rock Band, namely their high rate of breaking. The skit is filmed like a commercial for the titular product, a paste that you smear on the instruments, giving up to an "additional 10 minutes of gameplay." Derrick and Shawn use the Jam on the guitar and drum peddle, fixing it immediately. At the end, Rocco has a mouthful of the Rock Jam, which gives him a perfect singing voice to the song Maps. Throughout the skit, warnings appear telling the buyers to avoid contact with bare skin and that the free gifts included do not come complete.
This skit premiered at their Anime LA 08' panel.
