Fresh out of ideas on how to do something really bizarre, strange and just downright head-scratching?
Well, you could always pick up a few pointers from this genius.
Here is 54-year-old Petr Kapoun swimming in the middle of a frozen lake in nothing but a Speedo.
The self-professed health freak and freediver cut a hole in Lake Milada and swam “Free Willy” style underneath a large sheet of ice.
You can see him swimming alongside a yellow string that helped guide him from point A to point B without any hiccups.
Kapoun, who lives in the Czech Republic, credits his diet and strict workout regimen in helping him with the endurance to do the swim.
Talk about taking the “Polar Bear Plunge” to a whole new level of crazy.
Seriously, guys — we would highly advise you not to try this stunt at a frozen lake near you.
