Benson is easily the most short-tempered character of all. His short temper is usually contributed by the lack of productivity by Mordecai and Rigby, as they always prefer to slack off and play video games rather than doing their jobs. Benson often threatens to fire Mordecai and Rigby if they don't finish their work or do a simple task such as buying tortillas or going to a Karaoke Bar. Whenever they destroy park property or slack off, Benson loses his temper, turning varying shades of red.
