I was on a train once when a bunch of about 10 youths started running up and down the carriages trying to start a fight with someone. Anyone.
They were making heavy eye conctact with commuters hoping for a fight.
They got to one particular carriage with about 6 blokes of about 20 years old. Made heavy eye contact with one of them and he said "what the f*ck are you looking at".
Then it was on.
People were flying everywhere, the carriage was rocking back and forth. Security came, cops came, there was a man and dog team as well.
Turns out, the 10 youths who started it got their arses handed to them in a big way. I guess they picked the wrong crew to play games with.
The ones that could still walk took off into the darkness probably never to be seen again.
