In order to demonstrate what Prince Harry may have to do in an emergency during his Arctic trek, NBC special correspondent Ben Fogle jumped into freezing ocean water -- without a survival suit.
"I can tell you that was absolutely freezing," he said.
Matt was impressed: "That was absurd what you just did," he said.
Meredith was a bit more skeptical. "Is there altitude illness up there? What's the matter with him?"
Watch Ben's jump at the end of the video below.
