Jimmy Fallon recaps Trump’s Moon nuke plan, his odd rooftop moment, and more in a wild Tonight Show episode.

In one of the most surreal episodes of *The Tonight Show Starring Jimmy Fallon* in recent memory, the late-night host took aim at a flurry

of recent political and pop culture developments—headlined by former President Donald Trump’s eyebrow-raising plan to build a nuclear reactor on the Moon, and his even stranger rooftop appearance at the White House.

Fallon’s monologue, packed with punchlines and parody, tackled the stories with signature satire that blurred the lines between comedy and commentary.

“Welcome, everybody,” Fallon opened, greeting his studio audience with an almost dazed smile. “This was strange.” He then launched into the bizarre revelation that earlier that day, Trump had reportedly been seen walking aimlessly on the roof of the White House.

Fallon showed a mock photo of Trump pacing atop the historic building, joking that staffers shouted, *“Don’t do it, sir! Your approval rating isn’t that bad!”*

But Fallon didn’t stop there. According to his comedic take, Trump supposedly responded with a cryptic retort: *“I’ll come down when you stop asking me about the Epstein files.”*

The crowd roared with laughter, but the eerie mix of satire and reality sent a jolt of tension through the room. “If your grandpa was ‘taking a little walk’ on the roof,” Fallon mused, “you’d put him in a home, right?”

The real absurdity of the night, however, came from Trump’s recently revealed ambition to install a nuclear reactor on the Moon—an announcement that, even in a post-presidency world, still manages to dominate headlines and outrage.

Fallon riffed on the plan’s outlandishness, suggesting Trump originally wanted to *“clone dinosaurs and build a theme park”* on the Moon, but pivoted to nuclear energy when that idea was rejected.

“You can always tell how much sleep Trump’s getting by reading the news,” Fallon joked. “And this is a two-hours-of-sleep kind of headline.”

He continued, *“Trump wants to build the first combination nuclear reactor-slash-Pizza Hut on the Moon.”* The absurdity of that image—a radioactive, pizza-serving lunar outpost—was met with thunderous applause and laughter.

To explore the idea further, Fallon introduced a sketch featuring a fictional White House spokesman, “Dean Blake,” portrayed by a guest comedian.

Blake joined Fallon to explain the administration’s plan to replace the U.S. Department of Labor’s economic figures with Trump’s own “brand-new numbers.”

In a parody that skewered both Trump’s distrust of traditional institutions and his penchant for rebranding reality, Blake insisted that the number “zero” would be removed from math entirely because it’s “literally another word for ‘loser.’”

“Instead of zero, we now have ‘boof,’” Blake announced. “Boof is powerful. It doesn’t mean nothing—it means the most everything you’ve ever seen, ever.”

Fallon, playing the straight man, asked if there would still be a number to mean “nothing,” to which Blake replied, *“Jimmy, you’re talking in riddles.”*

From there, the sketch devolved into controlled madness. Numbers 1 through 5 were combined into a new number: “jaboingo,” which allegedly means “infinity boofs.”

Fallon tried to reason with Blake, warning about the dangers of falsifying economic data, referencing the Greek financial crisis as an example. But Blake dismissed it, saying, “They filmed *Mamma Mia!* there, and it was delightful.”

The exchange ended with Blake begging Fallon to post his bail using “boof-boof-jaboingo dollars,” which Fallon declined, ending the bit with a classic eye-roll and a wave to the cheering crowd.

But the episode didn’t stop at political chaos. Fallon shifted gears to more lighthearted fare by poking fun at McDonald’s new “Adult Happy Meal.” “Between this and Sydney Sweeney, one guy’s like, ‘Best week ever!’” he quipped.

Then, in a completely unexpected twist, Fallon was interrupted by Dan, a Tonight Show cameraman, who insisted he had written the “Song of the Summer.”

Fallon played along, giving Dan the floor. What followed was a hilariously awkward performance of an original song featuring lyrics like *“I have never used body wash”* and *“I use Tom’s Natural Deodorant.”*

Fallon eventually cut the song short, declaring a Jet2holidays jingle to be the true Song of the Summer, prompting laughter from the audience and mock outrage from Dan.

The host brought the show back on track with a sobering mention of wildfire smoke from Canada drifting into the U.S., impacting air quality across the Midwest and East Coast.

In typical Fallon fashion, he softened the grim news with a ridiculous “air quality scale” that used a series of increasingly absurd guttural sounds—*“Blehh,” “Ughh,” “Pffff,”* and so on—to illustrate the danger.

Finally, Fallon welcomed the night’s main guest, Lin-Manuel Miranda, celebrating the 10th anniversary of *Hamilton* on Broadway.

In a high-energy musical segment, Fallon and Miranda, backed by The Roots and using classroom instruments, performed iconic *Hamilton* tracks like “My Shot” and “Alexander Hamilton.”

The crowd erupted as Miranda delivered rapid-fire verses, and Fallon, ever the enthusiast, tried to keep up.

As the episode closed, Fallon summed up the chaotic energy of the night with a nod to his guest list: “Lin-Manuel Miranda is here tonight! Jordan Klepper is joining us! And we got great music from Chance the Rapper!”

The crowd cheered wildly, but the bizarre image of Trump pacing a rooftop and planning Moon nukes still lingered in the air.

Through a blend of satire, music, absurdity, and truth, Fallon delivered a Tonight Show episode that reflected the chaotic spirit of modern America—where even the most unbelievable headlines might just be real.
