Answer:

Hehe, this is a Chinese-English sentence that is said to be about Confucius' famous words, but obviously, it is an absurd joke. In fact, this is not what Confucius said at all, but what some diaosi teased and made up. It is not made up by foreigners. They just entertain themselves. You can see many such jokes in some post bars and websites. These so-called English jokes are self-translated according to Chinese meaning, and there are many grammatical mistakes, some of which you can't understand at all, so you can only laugh at them.

if you have to translate it into Chinese, this sentence can be translated into:

convinced say (should be said or said)

man who stands on toilet is high on pot.

Confucius said: stand in the toilet and be happy to pee in the pot.
