Instead of exaggerating nonsense, it is better to announce that clever, clever and humble epigram: "I don't know." What's good about this famous saying?
A man should be honest. It's not shameful to say what I don't know, but ridiculous to pretend to say what I don't know.
Confucius said that knowing is knowing, and not knowing is not knowing is wisdom. People who are really good at it will say: I don't know when they don't understand.
