Jon Stewart was asked to imagine how Donald Trump’s recent boast of “extreme intelligence” would hold up on the iconic game show “Jeopardy!”

And the “Daily Show” host didn’t hold back on how badly he believes the president would fare.

Trump would simply “blurt” out answers rather than wait for the right moment, Stewart joked, before launching into a theory:

“I’ve always felt that for intelligence — so where’s your brain located? It’s the head. ... If you think about it as a New York apartment building, it’s the water tower. And what’s the most important thing in the water tower? Pressure and the hydraulics of it. And what does Trump have? Chronic venous insufficiency. He’s got shitty water pressure!”

Stewart was referring to Trump’s CVI diagnosis revealed by the White House last year, which causes swollen legs and ankles, and which the president’s physician claimed had improved in the report from his recent medical examination.

The comedian continued:

“So what happens? ... No water pressure, no good shower, flushes are kind of hard to come by. So, as far as ‘Jeopardy!’ is concerned, this dude’s not getting the water pressure.”

The conversation between Stewart and his producers then turned to Trump’s recent explanation of how he came up with the insult “Dumocrat” and claimed that many people don’t know “dumb” has a “b.”

“How is this real?” he asked.
