In a surprising announcement Friday afternoon, President Barack Obama revealed White House Press Secretary Jay Carney resigned after serving as the top presidential mouthpiece for more than three years.

During his time at the White House, Carney earned a reputation for skillfully dodging and weaving when confronted by aggressive questions from the White House press corps. However, Carney avoided gaining a reputation for lashing out at reporters. Over the years, however, he has accumulated his feistier moments. Here at Business Insider, we gathered some of Carney's top clips and testiest exchanges.

• In September of 2013, Carney challenged Fox News Chief White House Correspondent Ed Henry to a "Crossfire" debate on the debt ceiling. "We're going to do this on 'Crossfire one day, I promise. And let's be clear: You'll be on one side and I'll be on another," Carney told Henry. "We need to help you with your facts." Watch below:

• Carney often feuded with Henry. In an exchange over press access in January of 2014, Carney interrupted Henry by insisting, "And you're leaving out that word for word, minute for minute, question for question, this President has answered more questions from the free and independent press, or at least as many as his predecessors."

• Carney had a particularly tense exchange with Karl in April of 2014 on the latest revelations surrounding the 2012 attack against the American diplomatic mission in Benghazi, Libya:
