Racsit?
Dough people?

Attack of the racsit dough people?
All sounds like a cheap horror film to me.

She said "Dull white people"
To be fair, I think it would have caused a bigger reaction if someone else on the show said "Dull black people" so perhaps it is classed as evidence of how the mention of black people is considered worse than that of whites.

Saying that black/coloured/foreign people are more exciting/lead fun lives.
And that an entire race is dull...would fall under the definition of racism.

The only reason it's overlooked is mainly due to the fact that she only called white people "dull" which isn't all that offensive.
