After Ryan Newman and Juan Pablo Montoya have a little contact that ended with Newman spinning out and losing quite a bit of time, Newman decided he was out for revenge. And he sure got it. By the end of the incident, Montoya's car had burst into one of the largest fireballs in NASCAR history. This is the incident that ignited one of NASCAR's great rivalries. 

PS: We cant help it "My name is Juan Pablo Montoya. You burned my car. Prepare to die."
