You're probably not singing your national anthem with as much passion as these people

Chile was once a colony of Spain. Maybe that's why on Wednesday the Chilean supporters that had gathered for the Chile-Spain World Cup match belted out their national anthem with battle cry-like fervor that may make you blush a little.

The cameras were rolling as the crowd -- which seemed to be dominated by Chilean fans -- screamed out their anthem and enthusiastically bellowed out the tune.

But the fans weren't alone. Also note how each player shown seems to be into the anthem as well. It's wonderful.

As a side note, you may notice the Chilean coach was about the only one not in on the action. Well, that makes sense: he's Argentinian.

So hit play, turn up the volume, and be inspired:

It seemed to help. Chili went on to win and knocked Spain out of the tournament.
