"USA! USA!" is a Regular Show short released by Cartoon Network on July 6, 2015. It features the "Places of the World" song from SDCC 2014.
The short begins with Mordecai and Rigby raking leaves. After Mordecai tosses the bag full of leaves into a bin like a basketball into a net, the two begin to chant "USA!" over and over. Suddenly, Benson arrives, and tells Mordecai and Rigby that there are other countries besides the United States. Mordecai and Rigby tell Benson that they do know other countries, so they decide to prove it.
They decide to do it through a rap song explaining the country and what they're famous for.
Once they're done, Mordecai and Rigby arrive back at the park, and Mordecai asks Rigby how many countries they went to. Rigby replies by saying that they went to all of the countries in world. Moments later, Benson arrives and chastises that Mordecai and Rigby left the park chanting "USA!", and nobody saw them for THREE months. Just as the two begin to explain their knowledge of other countries, Benson interrupts, and tells them to start working. He also tells them to get rid of a penguin who was following the duo during the song.
