Joel Kim Booster doesn’t want to get political. As a person who gladly and openly identifies as “dumb,” the Plainfield-raised comedian feels like in these starkly divided times we’re all trying to have intense conversations far beyond our education level. “Everybody thinks they’re a … geopolitical scholar,” he laments. Still, he told the standing-room-only audience for the first of two sold-out shows in the Upstairs Lounge at Schubas on Saturday night, he does have his own feelings of disappointment with the current commander in chief: “No matter what you think about or his policies,” he said seriously, taking on a slightly conspiratorial tone, “he’s very difficult to look at.” To Booster, Trump’s visage is “like a human face, but wrong.” True to his word, Booster — dressed smartly in a red and black plaid button-up shirt and jeans — never goes political with this bit, simply confessing wistfully that “I personally miss having a hot president.” Though he insists on his own dumbness, Booster’s playfully edgy comedy is anything but. And his body of work — which includes a half hour Comedy Central special that premiered last month and an album (the cheekily titled “Model Minority”) that came out Nov. 3 — is proof of that. He almost never goes for easy punchlines, relying instead on seemingly standard setups that he then subverts with a surprise angle. When his evangelical mother complains to him about Confederate statues being torn down, he tells her that he just doesn’t care, but not for the reasons the audience expects. He’s just too busy being addicted to his phone to bother with anything else: “I’ve got a little tiny computer in my pocket that’s got Candy Crush and gay porn,” he says. “Tear down all the statues and replace them with charging stations.” When straight men tell him that if they were gay they would be having so much more sex, he dismisses the stereotype, but with a winking twist: “No, you wouldn’t,” he says. “Because you would still look like that.” And when he recounts a fellow gay man telling him, “You’re the reason my parents don’t talk to me,” he doesn’t register offense, instead turning the statement back on his accuser: “You’re the only gay
