A video of a man slamming an entire 705 ml bottle of Jack Daniels whiskey in just 13 seconds has gone viral.
Will Williams of Caernarfon, Wales posted the video of himself performing the stunt on his YouTube page after it was filmed by a group of friends.
Williams now calls the stunt "stupid" and says he "regrets" slamming the bottle of whiskey.
Many comments on the video noted how dangerous the stunt was, and that it could potentially be fatal to drink that quantity of 80 proof whiskey in such a short amount of time.
