Late last night, this photo was posted on the Flickr page of Prime Minister Stephen Harper, and when you stop to consider it, it was kind of an incredible moment. Harper and former prime minister Jean Chretien, his one-time rival, were on a flight headed to South Africa for a memorial service for Nelson Mandela. Two of Harper's other predecessors — Brian Mulroney and Kim Campbell — were also on the plane, and they were set to meet a third, Joe Clark, in South Africa. The photo sported the following caption:
Sharing a laugh with former PM Chretien on the flight overseas
Which just goes to show that there's room for a little levity even during a serious world-historial event. On The Debrief tonight, George wondered what the Conservative prime minister said to the Liberal ex-prime minister that could elicit this kind of belly laugh.
