President of the United States, Barack Obama, has guest-starred on a highly-anticipated episode of Running Wild with Bear Grylls. 

Though the President was largely game for Grylls' tricks and surprises, there was one line he would not cross for the host: drinking his own urine. He reflected on the idea, "I suppose, in extremis, it's something that I would do - if the alternative was death. It's not something I'd make a habit of. And I probably wouldn't do it just for a TV show." 

The episode also saw Obama chow down on salmon which had previously been left behind by a wandering bear, alongside some tea made from catkins. Obama said of the meal, "I’ve seen some of the stuff Bear eats, and it’s gotta be something that doesn’t still have its legs and eyes on it. I want it not to be too recognizable. Bear’s a mediocre cook, but the fact that we ate something recognizable was encouraging. Now, the fact that he told me this was a leftover fish from a bear, I don’t know if that was necessary. He could have just left that out.”
