"Every now and again if I do something unexpected, the phrase we use is that 'the bear is loose'," said President Obama.
The bear on this unexpected occasion was adventurer Bear Grylls, and spending the day with him in the woods of Alaska, he said, was 'one of the best days of my presidency.'
"First of all, I'm not in the office. Second of all, I'm not in a suit," he said.
The pair were filming Running Wild which sees them survive a day in the wild wilderness. The episode was shot while the President paid a three-day visit to Alaska to highlight and observe the impact of climate change on the natural habitat of the 49th state.
Obama said he was ready for spending time in the wilderness, but was not so ready to eat what he was given by the British explorer, reports the Daily Mirror.
When he asked what was on the menu, Bear pulled out a half eaten salmon wrapped in moss.
"Well Alaska is the land of bear and salmon, we haven't got bear," he said, showing Obama the bloody fish. "Don't freak out too much but this was half eaten by a bear."
After finishing the "tasty" meal the President critiqued the former SAS soldier's cooking. "Bear's a mediocre cook. The fact we ate something recognisable was encouraging."
