For those in the audience that aren’t fluent in Linguinebolognesepicodegallo, the official language of the Whatusi, who are the tribe that runs the Intertunnel, allow me to clue you in:
These men are throwing monkeys at pigs. The reason these men are throwing monkeys at pigs is because there are men and monkeys and pigs present. No other explanation is necessary, really; if a man is handed a monkey, he’ll throw it at a pig — it’s genetic, not learned behavior. Ask any man what he’d do with a monkey if a pig ran by. He’d answer that he’d throw the pig at the monkey — or he’d lie. There are no other answers to that question.
I can not, however, offer any explanation for the music.
