"Last Week Tonight" host John Oliver on Sunday devoted his main segment to last week's Democratic National Convention.
President Obama spoke on the fourth night of convention proceedings, telling the audience that foreigners have trouble understanding how someone like Donald Trump could be the GOP's nominee.
"The rest of the world does not understand Trump's candidacy any more than they understand the menu at Guy Fieri's American Kitchen," Oliver said.
Oliver was emotionally struck by a speech from Khzir Khan, the father of fallen U.S. soldier Captain Humayun S.M. Khan, who said Trump "sacrificed nothing and no one."
"Wow," Oliver said. "That engendered in me a level of emotion that I did not think was possible after sixteen months of this depressing campaign and thirty-nine years on earth as a British person."
Oliver previously admitted his affinity for "human sweater-vest" Tim Kaine, Democratic nominee Hillary Clinton's running mate, during his "Late Show with Stephen Colbert" appearance last week. But he still had more to say on Sunday.
"His speech was exactly as boring as you would expect," Oliver said, "with the exception of his almost impressively bad Trump impression ... How is this man gonna win an election if he couldn't even win a game of Cranium?"
