“Daily Show” host Jon Stewart on Monday broke down President Donald Trump’s latest boast about his own brainpower as he repeatedly bragged about passing a test meant to check for signs of cognitive decline and dementia.

During a speech in Florida, Trump said he was shown images of different animals and had to identify the bear as part of the exam.

“I’m the only president to take a cognitive test,” Trump declared.

That left Stewart with one key question for the president.

“Why do you think that is?” he asked.
