John Oliver is comparing President Trump‘s recent stroll on the roof of the White House to a signature move by beloved Peanuts character Snoopy.

On Sunday’s Last Week Tonight, the host showed clips of Trump on Tuesday as he suddenly appeared on the White House flanked by Secret Service agents. Reporters down below, who were caught off guard, started lobbing questions at the president. Asked what he was doing up there, he replied: “Taking a little walk. … It’s good for your health.”

The action was reportedly related to a large ballroom he’s proposed building on the property. The 90,000-square-foot project will reportedly cost $200 million to build.

Saying he was planning to build “something beautiful,” Trump noted: “It’s just another way to spend my money for the country.” When asked to clarify, Trump replied: “Anything I do is financed by me; in other words, contributed. Just like my salary is contributed, but nobody ever mentions that.”

Joked Trump: “It … says a lot about the chaos of this administration, that the president just fully Snoopied on national TV.” He showed side-by-side images of Trump atop the White House and Snoopy sitting on top of his red doghouse.

“We’ll probably forget about it by next week, and the thing is, it got even weirder,” Oliver continued.

Oliver then cut to footage of another reporter asking what he was “trying to build.” Trump shouted down: “Missiles. … Nuclear missiles.” When the reporter asked him to confirm his said he was building more missiles, Trump then pumped his hand up and down at an angle to the side.

Said Oliver: “You know, that may actually be a perfect encapsulation of Trump’s presidency: A bunch of people yelling, ‘What the fuck are you doing?’ while he does a C-minus Hitler impression.”
