Prime Minister Stephen Harper was making good headway in a speech Monday night to supporters at a Regina-area farm when he suddenly stopped mid-sentence.
"Is someone throwing rocks at me," Harper said, turning to look behind him.
"Careful," he said chuckling.
It turns out someone was. Several boys and girls standing behind Harper had been using their campaign signs to flick bits of gravel from the floor in the PM's direction.
And once he turned his back, they started doing it again.
