Some mock Chinese proverbs (supposedly of the ancient Chinese philosopher Confucius) have been published since at least 1996:
 
ConFuSciouS SayS:
“man who run in front of car get tired”
“man who run behind car get exhausted”
 
The joke was published in a slightly different form on Reddit on June 30, 2016:
 
“What’s the difference between tired and exhausted?
When you run in front of a car, you get tired
When you run behind a car, you get exhausted.”
   
The “Confucius say” joke has been made into GIFs.
