I know one similar to this where a black man and his son are on an aeroplane, the plane gets into trouble and they have to lose weight so they get rid of everything they can but it's still too heavy. The pilot says, 'Im afraid we're going to have to chuck some of the passengers off, fairest way is alphabetiacally, so thats Asians then blacks, then *****, then darkies and we'll see how we are after that.' The son looks at his Dad worriedly, the dad says, 'Don't worry son, today we are ****!'
