I'm amazed Matt Lucas got away with the black woman airport skit. If say Jack Dee had done the same thing would the reaction have been different? I think comedy can be used sometimes to prod us and provoke a reaction as long as it's not vicious. Many like Frankie Boyle for his direct humour (I don't) and Ricky Gervais can be very near the knuckle. I think we are going down a rocky road if we have to analyse everything to ensure there isn't going to be someone, somewhere that may find something offensive.
