WATCH: Argentina U20s jump the passion shark during national anthem

There's a fine line between a patriot and a psychopath.

The Argentina U20s trod that line very carefully prior to their World Cup semi-final clash against Ireland at the Manchester City Academy Stadium. It was clear before the match even kicked off that the South Americans were very pumped up for this one. When it came time for the obligatory pre-match anthems, some of the Argentine youngsters looked like they were on the cusp of screaming themselves unconscious at several times during their rendition of Himno Nacional Argentino. Neck veins bulged, eyes almost popped out of their sockets, muscles clenched and presumably, the ears of everyone within a five-mile radius were left deafened as the Pumitas roared their national anthem. https://twitter.com/hicksimon/status/744930776836378624
