You thought it would never happen, but here's some kudos for former President Bill Clinton for standing up to the 9/11 conspiracy theorists.

Bill Clinton addressed a crowd in Minneapolis, Minnesota at a fundraiser for his wife's campaign on Tuesday.

Clinton's 50-minute speech, which started about an hour behind schedule, was derailed briefly by several hecklers in the audience who shouted that the 2001 terrorist attacks were a fraud. Rather than ignoring them, Clinton seemed to relish a direct confrontation.

"A fraud? No, it wasn't a fraud," Clinton said, as the crowd cheered him on. "I'll be glad to talk to you if you shut up and let me talk."

When another heckler shouted that the attacks were an "inside job," Clinton took even greater umbrage.

"An inside job? How dare you. How dare you. It was not an inside job," Clinton said. "You guys have got to be careful, you're going to give Minnesota a bad reputation."
