You heard the one from a week or so ago where the passengers on a plane didn't like the colour of the skin of a couple of fellows who got on, so they all walked off and the flight was cancelled and the two were taken in and asked if they were planning to blow the plane up, yes?

One of the choice quotes from a scared passenger on that one was that it was all very civilised, no one yelled names or anything, they all just got off. Right. Because it's only racist if you're rude about it.
