NBA All-Star weekend is always a time to have some fun. For Stephen Jackson, that fun may have involved poking some fun at Kyrie Irving.
Irving, as most already know, is a supposed "flat-earther." At the very least, he supports the idea that we shouldn't all just believe what we hear because it's what people tell us.
In any case, Stephen Jackson used that belief as the punch-line in his joke. During an Irving presser, Jackson stood in front of the crowd, spinning a (spherical) globe in front of Irving's face. Of course, it's nothing too crazy, but it certainly will put a smile on your face.
