A swimmer has broken his own record for the longest time spent in ice.
Josef Koeberl, from Austria, spent more than 2 hours and 30 minutes in a giant glass box filled with blocks of ice.
He was surrounded by more than 200 kilograms (440 pounds) of ice cubes inside the custom-made structure, which was erected in the town square in Melk.
And if that wasn't enough, he did it all while only wearing a pair of colourful swimming trunks to cover his modesty.
Speaking about the incredible effort, which saw him beat the current record by 30 minutes, Koeberl said it was all about having a positive mental attitude.
He said: "I'm fighting the pain by visualising and drawing on positive emotions so I can dampen this wave of pain. That way I can endure."
According to his team, Koeberl also now holds the record for exposing the body to ice for the longest time.
After stepping out of the box, the thrill-seeker said it felt 'great' to have the sun beating down on his back again. I bet it did.
He added: "I'll manage to put my socks on myself. The first thing that has to warm up are your feet."
But while the idea of doing this all over again would be the last thing on most people's minds, Koeberl is already planning on trying to beat his own record for a second time.
According to reports, he hopes to beat it once again next year, with Los Angeles set to be the location for the attempt.
But this isn't the only crazy stunt we've seen in recent weeks.
The stunt saw the 47-year-old float through the air using a bunch of helium balloons - much like the house in Up.
The feat, which was said to have been '10 years in the making', was originally due to take place in his hometown of New York City on 31 August, but due to windy conditions in The Big Apple it was moved to Page, Arizona, today (Wednesday).
Blaine reached heights in excess of 24,000ft and the flight and took around an hour. You can see his flight path here.
Following a series of rigorous checks, Blaine's daughter Dessa attached his final balloon and he began to drift up into the blue skies at about 4pm, removing ballasts to ascend further and further.
As he continued to rise, Blaine used his long-honed breathing and purging techniques to maximise his oxygen intake.
