What should have been a day of sledging thrills turned into a string of near-disasters in California after one person fell into an icy lake.
As they overshot the edge of the ice and fell into the bitterly-cold water, flailing and waving their arms in panic, pals to rushed to their aid.
But it begs the question: How many people does it take to rescue a man who falls into an icy lake?
And the answer? Well, if this video is anything to go by ... lots.
The situation in Wrightwood, California, rapidly became a mass rescue attempt, involving ropes, rubber rings and plastic sledges.
But as dozens of people joined in, several more crashed though ice.
One witness captured the amazing drama on video and posted it on The Tubez website.
Another could be heard saying: "That's seriously not funny ... he can't swim", while a companion screamed: "Call 911!"
Some of the victims remained in the water for up to nine minutes before they were eventually pulled out.
No one was seriously hurt.
