Prime Minister Stephen Harper found his stump speech interrupted by bangs and whistles today.
He was making good headway in the speech to an enthusiastic crowd when the loud whistle of exhaling air interrupted.
"Friends, the opposition is ....," he said before being cut off.
Harper stopped and there was a brief moment of alarm as everyone tried to figure out the source of the sound.
Turns out someone's thunder sticks - the inflatable wands used to make noise - had gone flat with a whistle.
"You had the RCMP excited for a minute there," Harper said. "We'll leave the hot air for the Liberal rally."
And then after a pause, Harper added one more thought.
"I started talking about the Liberals. I thought that noise might have been some other kind of wind," he said.
The crowd was just settling from that incident when a loud boom filled the room. Turns out that a reporter had inadvertently walked into a glass panel, thinking it was an open door.
