Fist Pump

Fist Pump is a rock n roll band. The peak in their career was apparently around the time Mordecai and Rigby were in 3rd Grade. They reunited after they came of a jail and rehab to host a reunion concert at Slammers. Mordecai and Rigby got extra work from Benson (who does not approve of the band) so they can get tickets to see them. They start their concert with a flying fire breathing big rig.
