Jimmy Fallon spent a second straight night ribbing President Donald Trump's new Great American State Fair on Thursday, saving his sharpest jab for a petting zoo bit aimed squarely at the president's cognitive fitness.
The "Tonight Show" host took aim at the fair, which opened to the public on Thursday on the National Mall as part of America's 250th anniversary celebrations, rattling off a list of fictional attractions inspired by Trump.
"The fair has everything," Fallon said, according to Mediaite. "There's a giant Ferris wheel, there's a carousel. They even have a Trump approval rating roller coaster, which has the biggest drop in history."
He kept going with a swipe at the president's physician, joking that organizers had also "hired Trump's doctor to guess what you want your weight to be. '150?' 'Sure.'"
Fallon told the audience that fairgoers could visit "a petting zoo with some of the animals Trump named during his last cognitive test." Imitating the president, he deadpanned: "Horse, duck, stripey horse."
The joke landed against a backdrop of Trump's own repeated boasting about his performance on cognitive screenings, including the MoCA dementia assessment.
During a May 1 rally at The Villages, solidly GOP-leaning retirement enclave in central Florida, Trump abandoned his One Big Beautiful Bill sales pitch to revisit the tests.
"I don't think Obama could pass it. Biden? Give me a break," he told the crowd, describing how he was asked to name animals. "You know, the first question's very easy. It's a lion, a giraffe, a bear, and a shark. They say, 'Which one is the bear?' And everybody says ohhh– 30 questions. Very standard, very standard test, but very tough around those last 10 questions."
Trump also told the audience that one doctor had described him as "a mad genius."
The president's mental fitness has drawn formal scrutiny on Capitol Hill.
On April 14, Rep. Jamie Raskin (D-MD) introduced legislation to create a 17-member commission empowered to assess whether a sitting president is fit to discharge the duties of the office under the 25th Amendment. The bill was offered with 50 Democratic co-sponsors but faces no path to a vote in the Republican-controlled House.
