If you try to heckle President Barack Obama, be warned: He will heckle you right back.

On Tuesday, Obama was interrupted by a pair of protesters at a rally for Hillary Clinton in North Carolina.

“Is somebody hollering again?” Obama asked the crowd. “You know what? Here’s the deal. Try to get your own rally. You gotta get your own rally. See, if you can’t get your own rally, don’t come mess up somebody else’s rally.”

The protesters were wearing T-shirts that read “Bill Clinton Rapist,” in reference to allegations against the former president recently given new life by Donald Trump. They were escorted out of the rally by security.

Earlier on Tuesday, a similar group of protesters interrupted a rally in Florida with Hillary Clinton and former Vice President Al Gore. The conspiracy website Infowars is currently offering readers thousands of dollars to stage such interruptions in front of television cameras.

Obama is no stranger to shutting down hecklers, frequently telling protesters to vote instead of boo. This summer, he grew particularly irritated when he was heckled in the White House.

“You’re in my house,” he said. “It’s not respectful.”
