At times, the Mustang versus Camaro storyline is as sophisticated as The Itchy and Scratchy Show, the television-show-within-a-television-show created for Matt Groening's jaundiced, cartoon American family. While these two pony cars take turns playing tireless cat or ruthless mouse, one thing remains constant: they fight (They fight. They fight, they fight, they fight. Fight, fight, fight! Fight, fight, fight!) with little purpose other than antagonizing the other or settling the score.
