This is how obscenely rich people fight: they call each other poor, and insult one another’s television shows, all over Twitter. Welcome to the latest round of the Mark Cuban/Donald Trump beef. Per the Dallas Morning News: “Mavericks owner Mark Cuban and a similar popular entrepreneur Donald Trump went at each other Monday afternoon on Twitter over their million-dollar donation proclamations. Some of the back-and-forth Twitter banter: @realDonaldTrump: ‘Dummy @mcuban is at it again trying to use me to get publicity for himself! … @mcuban tries so hard to be a star and he truly doesn’t have what it takes and never will!’ [...] @mcuban: ‘.@realDonaldTrump Ok DJT, Im already in 1mm for #Sandy victims, if it all is dedicated to #Sandy rebuild , here is what i will do…@realDonaldTrump: ‘Only 1 mill. dollars @mcuban? Offer me real money and I’d consider it. Your team and networks lose so much money I doubt you have much left!’”
