Fist Pump is a band comprised of four members, intended to be for third graders according to Mordecai, but in the commercial advertising the concert, it was to have been for eleven to fifteen-year-olds. Mordecai and Rigby got extra money for doing extra work for Benson (who does not approve of the band) so that they can buy tickets to see them at Slammers. It seems that Skips likes them and according to their promo commercial, they also used to be in jail and rehab. So far, their only appearance is in Caffeinated Concert Tickets. A Fist Pump album is seen in Margaret's car in Butt Dial. They are also shown in Caveman when Mordecai and Rigby teach Gregg about music.
