I generally don't like it when the bus passes someone at a stop but I ALWAYS think it's funny when someone at the stop is acting too cool for school and doesn't look at the bus when it's approaching so it passes and they freak out waving their arms and everything as it goes by. In the scenerio I am on the bus and it's the funniest when it happens to Paris Hilton-looking, posh girls who think they're too good for the bus.
Generally I find failed pretention very funny.
