Racism is so not funny

I was absolutely appalled at work when a colleague told me the one about the black Jewish boy*. I think that this sort of thoroughly offensive 'humour' should have been left dead and buried in the 1970s, along with Bernard Manning.

* The boy asked his Dad whether he was more Jewish or more black. His Dad replied that it was a difficult question and asked why it was relevant. "Well" said the little boy "The lad at the end of the road wants to sell his bike for £20. I'm not sure whether I should offer him £10 or just nick it".
