The B.o.B flat-earth story will not die. Earlier this week, we learned that the once-promising Atlanta rapper believes both that the planet is flat and that there is a Jewish conspiracy to make you think that it’s actually round. He endorsed a prominent Holocaust denier in a rap song. It’s all very weird and sad. This naturally led to B.o.B feuding with the famous scientist Neil DeGrasse Tyson, who has been nice enough to say that no, the world is not flat, without being an asshole about it. Last night on The Nightly Show, Tyson turned up and transformed the entire episode into a comedy bit, giving B.o.B a strong dose of real talk and linking his weirdness with “a growing anti-intellectual strain in this country that may be the beginning of the end of our informed democracy.” He managed to rip him apart in a weirdly humane way without even pointing out that “Nothin’ On You” is a terrible song. He didn’t even mention the anti-Semitic stuff, which means he had the kid gloves on, and he still annihilated B.o.B. Watch it below, via Vulture.
