for me the act wasn't actually that funny, abit poor taste, but at the end of the day, if your white and trying to do a comedy sketch that includes black people, and you don't have any black people to do it you are at a bit of a loss.
is it any different to people like avid merrion using black masks etc when hi does bo selecta, what about spitting image useing black puppets.
you have to draw a line somewhere. yes it was poor taste but it wasn't a deliberate racisit attack. they were just trying to be funny and failed miserably.
i have dual nationality and my other passport is ozzy, and yes the ozzies can be abit backward when it comes to multicultural issues. but i think we take it to far in this country.
