On Monday night’s episode of “The Daily Show,” Jon Stewart poked fun at President Donald Trump for some unusual behavior during a bill signing.

Stewart opened the show by explaining that Trump “did a solid” by signing a bill that fast-tracks the “FDA process for novel psychedelic drug treatments for veterans suffering from all forms of PTSD and other psychiatric conditions, including addiction.”

The show then cut to Trump in the Oval Office talking about a study on the psychoactive drug ibogaine, which showed that, in the president’s words, users “experienced an 80% to 90% reduction in symptoms of depression and anxiety within one month.” Trump then joked, “Can I have some, please? I’ll take it. I’ll take it, whatever it takes.”

“Oh wow. He’s depressed, too,” Stewart quipped. “Hey, don’t be depressed, sir. Trump won’t be president forever. But I have to say, there are little moments in these Oval Office gatherings that are somewhat revelatory of the president’s psyche, and really a good starting place for any accredited mental health professional.”

Back at the Oval Office, Trump said to a room full of aides, “I don’t have time to be depressed. If you stay busy enough, maybe that works too. That’s what I do.”

“I don’t think Donald Trump should treat that with hallucinogens, but if he did, would we even notice?” Stewart said. “If he took them, he’d be like, ‘They’re eating the cats and dogs! Right near my beautiful ballroom. By the way, did you know I’m Jesus?’”

He added, “You know what, though? Maybe he’s already taken them, given how intensely he focused on the signing of this bill. I mean, he signed the shit out of this bill.”

Stewart then cut back to Trump, who took his time signing the psychedelics bill before saying, “That’s a good one. See that, Joe? You think Biden can do that?”

“’Have you ever really looked at your signature, on weed?’” Stewart joked. “And look, I think this is a good thing that he did, and this is not political, but that was weird as shit the way he signed that.”
