Benson trusts Muscle Man far more than Rigby and Mordecai, as established in "Appreciation Day" and "My Mom." He does fire Muscle Man though in " Don " and " Under the Hood ." Benson also seems to understand Muscle Man and his antics, as demonstrated in " But I Have a Receipt " and " Free Cake ," not yelling at Muscle Man when he put "My Mom" on the list.
