For centuries, Vikings have been eating skyr, a thick, creamy yogurt as a source of energy to defeat their opponents and survive in some of the harshest climates known to man. Skyr is full of protein, flavor, and tradition. This is why the world's strongest man, Hafthor Bjornsson, and Terry Crews both eat it to supplement their workout regiments. So Unnar Beck Danielsson partnered with Hafthor, Terry, and Dylan Sprouse to introduce Thor's Skyr to the rest of the world. While this may seem like a random collection of celebrities, they're all very much in touch with the Icelandic culture, and funny enough, Terry actually means Thor in the old Norse language. In today's episode we chat with the cofounder of Thor's Skyr, Unnar, about:

• why going into Walmart was a mistake

• The decision to make Terry Crews a founder instead of an ambassador

• How he honed his salesmanship by convincing diners in his restaurant to try fermented shark
