While campaigning for Republican Senate candidate Jeff Flake in Arizona, Sen. John McCain got feisty with some hecklers in the crowd.

In addition to telling them to "shut up," McCain also called the hecklers "jerks."

"Listen, even here in this wonderful square, jerks are allowed," he said. "They're allowed."

In a coup de grace, McCain stuck his tongue out at his harassers and made an animated gesture with his arms.
