I believe the word you are referring to is 'kike'.
Oh i don't mean like stand up commedians...i mean people won't make fun of themSELVES for fear of offending others...now THAT my friend is rather messed up...i belive so at least...Personally, if a comedian needs the rules of PC to be abolished in order to do his job, then i'd argue that he isn't all that funny in the first place, as he's dependant on slurs and not his natural comic genius.
