A wise man believes half of what he sees, And nothing of what he hears?

Question

Where did this phrase come from? I can't find it

Answer 1

"Believe nothing of what you hear, and only half of what you see."

This is most likely a variation from 'The Proverbs of Alfred' (~13th century)

Answer 2

A wise man once told me this: NO MATTER HOW MUCH YOU SQUARM AND DANCE THE LAST TWO DROPS GO IN YOUR PANTS.
