You won't get to play this one often, but I just did.
Watch a couple of suburban yahoos seriously offend an older east Indian man (I missed the offending comment or action).
Listen as the old man seriously cusses out the yahoos with some "colourfully" translated insults.
Watch as one of the yahoos gets up and spits at the old man, precipitating a full-blown fist-fight.
At this point the driver pulls over and puts the yahoos off the bus. One of the yahoos decides to swing around and take a Parthian shot at the old man that nearly knocks him down.
