On Sunday's edition of "Last Week Tonight," host John Oliver lambasted President Donald Trump's statements about his lies about having "tapes" of his conversations with ousted FBI Director James Comey.

Oliver played a clip from "Fox and Friends" of Trump saying he'd raised the specter of recordings of the conversations to "keep Comey honest" in his testimony before Congress, which he went on to congratulate himself, saying, "It wasn't very stupid" of himself.

"What the fuck was that?" Oliver demanded. "Whenever Trump talks, it's like a lottery machine that spits out words and a Speak and Spell that just fell into a toilet."

"Wow," Oliver said, "'It wasn't very stupid.' Let's break down what just happened there."

He continued, "He didn't just casually admit to misleading the American public. He also implied that doing so may have swayed Comey's testimony, which -- if that was his intent -- could constitute witness tampering. And on top of that, he then implied he made Comey tell the truth about their conversations, seemingly verifying Comey's account, which is incredibly damaging to the president."

"So," he said, "Trump might actually be right, it wasn't very stupid -- it was extraordinarily stupid."
