SALEM, New Hampshire -- Speaking to a packed high school auditorium just hours before polls open in the nation's first primary, Hillary Clinton offered her closing argument and faced down hecklers to loud and sustained applause.

Fifteen minutes or so into Clinton's speech, two high school age children stood up with signs reading "Iron my shirt" and began to chant. Clinton tried to talk over them as security personnel rushed to remove the miscreants.

After a futile minute, she stopped. "Ah, the last remnants of sexism," she joked. The hecklers removed, Clinton used the moment to her advantage. "As I think was just abundantly demonstrated, I am also running to break through the highest and hardest glass ceiling," she said, drawing a standing ovation.

Clinton later offered to answer any questions the crowd might have. "If there's anybody left in the auditorium who wants to learn how to iron his own shirt, I'll talk about that," she said.

Later tonight, Clinton heads to Manchester where she will hold a rally with husband Bill just three and a half hours before residents in Dixville Notch and Hart's Location head to town halls to cast the traditional first ballots of the New Hampshire primary.
