Researchers at the University of Arizona released a study Monday showing a causal relationship between raising one's voice, pushing people in the chest, and getting what you want more quickly. 'These results certainly go against common wisdom,' said visibly bruised and flustered sociologist Rene Pfaff, who found that subjects in the so-called 'jerk group' received rewards an average of 45 seconds faster. 'Once we ran out of the rewards, the participants began shaking down our research assistants for money.' The study also concluded that gratuitous swearing accelerated the process by as much as 40 percent.
