We already know that the cognitive test Trump keeps banging on about isn't actually meant to be hard, but nonetheless the president won't stop bragging about it — recently boasting that he's "the only president to take a cognitive test."

"You're the only president to take the cognitive test?" asks Jon Stewart in the Daily Show clip above. "Let me ask you a question: Why do you think that is? Why do you think that you're the only president that that happens to? That for some reason every time you go to the doctor, which is a lot, the doctor's always like, 'Hey while you're here...'"

Stewart then plays another clip of Trump talking about a complex mental arithmetic question that they apparently also asked him, and which he claims to have answered correctly.

"No, Trump is a regular Stephen Hawking," says Stewart. "That's what it is. Although I thought the only thing they had in common was being in the Epstein files."
