An unsuspecting car salesman gets the test drive of his life in this week's top viral video from Pepsi Max.
The soft drinks brand speeds to the top of this week's Viral Chart with its hugely-popular video showing Nascar driver Jeff Gordon - in disguise - giving a poor guy the fright of his life.
The video has been shared more than 770,000 times on social media this week, making it by far and away the number one video in this week's chart.
Second place on the chart goes to another prank video, this time from Carlsberg. The beer brand garnered more than 80,000 shares after tricking friends into believing they needed to turn up to an illegal poker game to bail their buddy out of a particularly dodgy situation.
The charts are compiled with the Viral Ad Network and are based on the number of shares each video has received on social media over the last seven days.
