Seth Rogen regales The Late Show with his adventures in Trumpland, hotboxes Stephen Colbert

Calling stoner giggle-bear Seth Rogen “an avatar of ‘what’s the big deal?,’” Stephen Colbert congratulated first guest and Canadian ambassador of garrulous good will Seth Rogen on his home country’s recent decision to legalize recreational marijuana on Friday’s Late Show. “Now that marijuana’s legalized, is your work done?,” Colbert asked the clearly delighted Rogen, adding, “Can you return to your home planet?” Instead, Rogen accepted Colbert’s invitation to take part in that endearingly goofy recurring bit where Colbert and his guest stick their heads uncomfortably close together inside a cardboard box, where Rogen, in response to Colbert’s perhaps unwise question “Are you stoned right now?,” withdrew, only to return with a lungful of presumably real pot smoke for them both to enjoy.

Before the on-air hotboxing, however, Rogen talked Preacher (returning on Sunday), noting that the fact that its third season will bring in Hitler as an antagonist means that Mercedes is not on board as sponsor. He also had some unique insight into Donald Trump’s recent trip to North Korea, since, as he says, his film/international incident The Interview was about “an egomaniacal TV host who gets invited to North Korea to meet its leader, and he does it an an attempt to gain legitimacy on a global scale, and when he gets there he gets tricked into thinking he’s a super-nice guy.” Except, as Rogen notes, “ we have a third act where he finds out that he’s bad.”

Continuing his surreal adventures in the land of those who think jolly recreational pot smokers like him should be locked up and not free to tell embarrassing stories on late-night TV, Rogen also told Colbert about a recent speech he gave deep in the heart of Republican country. Accepting an invitation from Mitt Romney to speak about his work on behalf of Alzheimer’s research, Rogen told Colbert how he was blindsided by a pair of enthusiastic young fans—and their glad-handing dad, Paul Ryan. Asked for a picture by the House Speaker, Rogen said his response was a hearty, “No way, man!,” adding, “Furthermore, I hate what you’re doing to the country at this moment and I count the days ’til you no longer have one iota of the power that you currently have.” His Canadian politeness warring with his political conscience left Rogen feeling a little guilty on behalf of Ryan’s kids, but, as he explained, “It’s not their fault, but they should probably learn that if they like a movie or a song, the person who made that probably doesn’t like their dad that much.”

Rogen also told Colbert about making an “if he only ha a brain” joke at the expense of conference attendee Anthony Scaramucci. There, too, his Canadian qualms were assuaged when Scaramucci later called his agents looking for a hook-up, claiming that he and Rogen had “really hit it off.” Which suggests that, while the fame-hungry former GOP spokesperson might have a functioning brain, he does appear to be missing some parts from the shame and dignity centers thereof.
