A lengthy rain interruption resulted in the Canadian Grand Prix becoming the longest in F1 history. But there was ample reward in store for those patient fans who sat through the four hours, four minutes and 39 seconds that the race lasted.
On the final lap, Sebastian Vettel cracked under the pressure exerted by the trailing Jenson Button and skidded wide. Button gratefully surged past him in a flash and sealed a last-gasp victory. It was evidence that Vettel, for all his brilliance, is not yet the finished article.
Button was having an eventful race to put it mildly, having previously collided with Lewis Hamilton and Fernando Alonso, forcing both to retire.
"I think Lewis thought the chequered flag was in Turn Three," he joked at his team-mate's expense.
