The president was having none of that.
"OK, you know what? No, no, no, no, no... Hey, you know what, you're in my house," Obama said, drawing a huge cheer from the crowd.
Obama continued after the heckler was removed from the room.
"As a general rule, I am just fine with a few hecklers, but not when I'm up in the House," Obama said. "My attitude is if you're eating the hors d'oeuvres, know what I'm saying, and drinking the booze... I know that's right. Anyway."
It's hard to make out what the heckler was saying, but very easy to tell that they have an extremely annoying voice. The Associated Press reports that it had something to do with immigration reform.
