Cool Bikes

S3, E7: Mordecai and Rigby beat Muscle Man and High-Five Ghost in a cart race and pick up some girls who have some flat tires. However they soon destroy the cart so Benson punishes them by taking away their cart privileges and forcing them to ride kiddie bikes. Angered at the “uncoolness of the bikes Mordecai protests the decision due to them taking away their cool appeal. He strikes a deal with Benson: if Benson admits that they're cool then they can get their cart privileges back. Mordecai and Rigby do whatever they can wearing cool sunglasses dressing up in stylish clothes but Benson refuses to admit that they are cool. Trouble ensues when the cool police arrest Mordecai and Rigby for being too cool and they are taken to a distant planet for trial. Benson is then called over as a witness where he finally admits that Mordecai and Rigby are cool. The judge determines their sentence - death. Mordecai Rigby and Benson all escape alive after setting the planet to detonate.
