Alien: Human John, I have another question!

Human: Okay, what is it this time Zelbar?

A: I was observing one of your human broadcasting services and I stumbled upon something strange.

H: Oh dear, what did you find?

A: I do not know, it appears to be some sort of stadium with a war ceremony and humans singing war chants

H: What? Could you show me, please?

A: Certainly. pulls up footage from a football/soccer match with people singing we will rock you

H: Oh, that's a football match, it's a sport.

A: A sport? As in a form of exercise?

H: Yes

A: Then why are there so many humans there? There only appear to be twenty-two humans actually partaking in the sport.

H: Oh, those are the supporters

A: Supporters?

H: Yeah, they like one of the teams, and are there to show their support, and because it's fun.

A: Opening footage of hooligans Why are they fighting?! Does something depend on it? do the winning team's supporters get something?!

H: They don't really get something, they just... feel very strongly about their teams and use it as a way to show support. And some also just want an excuse to fight

A: Then why do your authorities allow it!?

H: Humans need entertainment, they'd get angry without it

A: Are no measures taken?

H: oh they are, whole riot squads are brought in for high risk games, the most violent fans get arrested and banned from the stadiums, there are a lot of police officers there at those games, and most of the time that's enough

A: You police are there and people still fight!?

H: Some of them fight the police on purpose

A: For a game?! A sport?!

H: yeah

A: ... barbarians
