Flat-Earth Argument Results in Rap Battle (npr.org)

New submitter mjjochen writes: A little something to make you smile (or cry). NPR reports on astrophysicist Neil deGrasse Tyson calling out rapper B.o.B. in a Twitter (& rap) argument over the status of the earth (are we round or flat?). Rapper B.o.B. references the usual conspiracy theories to support his case in his throwdown (music). Neil deGrasse Tyson responds (actually, his nephew does), on why B.o.B.'s points are not very well-informed (music). As Tyson puts it, "Duude — to be clear: Being five centuries regressed in your reasoning doesn't mean we all can't still like your music." Shall we start leeching the four humors from the body again to achieve balance? Hrm.
