Because the main point of this video isn't where these students are from, but rather their (highly amusing) state of inebriation. A state of inebriation that caused them to a) interrupt this American football report from the Dallas Cowboys' stadium and b) scream a lot about "Johnny Football" who, it turns out, is the Heisman Trophy winner Johnny Manziel. Who plays for Texas A&M University. See? It all makes perfect sense!
Yes, drunk people interrupting news reports may be ten-a-penny. But this one really is one of the finest.
