Jimmy Kimmel is determined to prove that aliens are real. Not content with persuading former US President Bill Clinton to talk about Area 51, the talk show host took full advantage of having current US President Barack Obama on his show as well.
It didn't take him long to get onto the subject, suggesting that if he had been made President the first thing he would do is head straight down to Area 51 and find out for himself.
Of course President Obama wasn't going to fall for that trick, instead joking that that's precisely why Kimmel probably wouldn't be President.
When asked seriously if he knows anything about the existence of aliens, the President simply responds "I can't reveal anything."
