If you're going to keep repeating that mantra ad infinium, the least you could do is change up the vocabulary a bit from time to time.
I looked up "pot calling kettle black" in my authoritative
Dictionary of Useful Idioms for Useful Idiots. It gave only one example, but it was apt: "For example, for Thomas Graves to accuse anyone else on earth of using repetitive vocabulary and repeating the same points to the extent of near-maddening tediousness would constititute a paradigmatic example of the idom 'pot calling kettle black.' This example is so extreme that it is unilikely ever to occur in the real world, but it does serve to illustrate the idiom in its most extreme form."
