When the Paraguayan and Venezuelan footballers aren't playing football, turns out, they're kickboxers, or ninjas (what ever suits you). After the match was decided on penalties, with Paraguay going through to the final, the teams decided that it wasn't the end of things.
During the match, Venezuela hit the woodwork twice, had a goal (stupidly) called for offside, and had numerous chances that looked like they were going in spectacularly saved. I can understand the frustration of the Venezuelans came from. It's hard to tell who started the whole ordeal, so I'll just assume it was the Venezuelans in the maroon.
At least they're passionate. Or dicks. Both?
