I wouldn't exactly say I am defending him. His humour is pathetically puerile and I can't stand to watch him on TV. But he is correct that he didn't use the n-word. He alluded to it and got a childish snigger out of not actually using it while alluding to it. If the rhyme was unknown, nobody would be able to decipher any words out of that mumbled line. He is relying on the fact that everyone knows what the line is meant to be, and that it is no longer acceptable to use it, to get a cheap laugh.
Unless the audio has been doctored, he is using it by any reasonable standard. He is clearly NOT using a well-known alternative such as "tiger" which was what I was told to use when I was a child. And it doesn't really matter that we have to be familiar with the rhyme to decipher what he is saying (or using) because much of our speech is indecipherable if taken in isolation and requires co-text to make it coherent.
