CAERNARFON , Wales, Sept. 5 (UPI) -- A Welsh man who posted a YouTube video of himself downing 23.6 ounces of Jack Daniels bourbon in 13 seconds said he now "deeply" regrets the "stupid" stunt.
The video, filmed by friends, shows Will Williams of Caernarfon biting the seal off a 23.6-ounce bottle of 40 percent proof Jack Daniels bourbon and chugging the entire bottle in only 13 seconds.
Williams instructs his friends in the video to "Neknominate that," a reference to an online drinking game based on dares.
"It was something that I did jokingly and regret deeply," Williams told the North Wales Daily Post. "Straight away, I knew it was a stupid thing to have done."
Williams said he was shocked to see the video accumulate more than a million views.
"When I posted the video, I only expected friends to view it really," he said.
The amount of alcohol Williams consumed in the video is more than seven times the daily amount recommended by Britain's National Health Service.
There was no word Thursday on whether Williams' regrets included expelling the liquid the same way he ingested it after the video stopped recording.
