It's Spock versus Spock at the top of this week's Viral Video Chart as Star Trek original Leonard Nimoy takes on new pretender Zachary Quinto in a car race for Audi.
Quinto, who plays the legendary character in new Star Trek film 'Into Darkness', wins the race to the golf course in his Audi but ultimately the original Spock gets the better of him with his trademark Vulcan nerve pinch.
The spot has been shared almost 100,000 times over the last seven days, enough to dislodge Evian's dancing babies from the top spot and knock IBM's World's Smallest Movie into second place.
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.
