2 Guyz N the Parque is the name of the two street performers who sang "S.I.M.P. (Squirrels In My Pants)" in the episode "Comet Kermillian". "S.I.M.P." is sung in a hip-hop beat. They both made a few other cameos in other episodes. A running gag in "Comet Kermillian" was that they kept getting "served". Parque is the Spanish term for "Park". Some of the lyrics of "S.I.M.P." suggest that the pair may be college students looking to make a bit of extra money.
