Barack Obama says it would have been fun to run against controversial Republican presidential hopeful Donald Trump in a US electoral campaign.
"I would've enjoyed campaigning against Trump. That would've been fun," the US president said in the interview in GQ magazine.
Elsewhere in the interview Obama was asked about which Game of Thrones character he thought was most like Trump.
"Uh? I don't think any of them rise to that level," Obama replied.
He also said that one of his "guiltiest pleasure" TV shows is Big Break, a program on the Golf Channel that he defined as "silly" but that he finds "really relaxing".
Obama also compared himself in the interview with American football player Aaron Rodgers, quarterback of the Green Bay Packers, in the sense that he believes he has the same quality of "not getting flustered in what's around me".
At the same time, the president said that what happened in December 2012 at Sandy Hook in Newtown, Connecticut, where 20 very young children were killed in a school shooting, remains "the worst few days of my presidency".
As for his "most entertaining conspiracy theory", he said it was the one that claimed some military exercises ordered by his government in the state of Texas "were designed to begin martial law so that I could usurp the Constitution and stay in power longer".
Obama also said that he has gone five years without smoking because "I made a promise that once health care passed, I would never have a cigarette again. And I have not".
After leaving the White House, the president said he doesn't see himself occupying a seat on the Supreme Court since "I don't have the temperament to sit in relative solitude and just opine and write from the bench. I want to be in the action a little bit more".
Obama named the only people whose phone call he would answer if he were dining with his wife Michelle on a "date night": his daughters "Malia and Sasha, and maybe my mother-in-law, my national security adviser, Susan Rice, and Denis McDonough, my chief of staff".
