A person made you mad, you got upset and overreacted. What did you do?

A lot of people, including myself on occasion get realy upset when people “wrong” us. Sometimes we tend to overreact and do something over the top. Whats your story, or a friends story of overreacting?

example; I was driving with my dad on the highway. A small subaru STi cut him off and then proceeded to break check him. He got super pissed, rolled down his window and threw a chocolate milkshake onto his windshield. It was interesting to say the least.
