This is a whole new level of doing something for a good picture/story.
A man was doing some marine-research and suddenly "felt pressure" around his hips, and knew he was inside of a whale. He was somehow able to keep his cool, hold his breath, and wait until he was released. When he finally got up to the surface, he just wanted to make sure there were some good photos, of course.
Watch the clip and see the pictures and be amazed that he's telling this story with such calmness.
