A lawyer, an economist, and a teacher were going to the bathroom. The lawyer gets done, washes his hands, and then proceeds to use almost the entire roll of paper towels to dry his hands. He says "I was taught to be thorough."

一個律師、一個經濟學家、一個教師同時進廁所。律師上完後洗手，接著幾乎用了整捲擦手紙來把手擦乾。他說：「我受的教育是做事要徹底。」 

The economist gets done, washes his hands, but uses only one paper towel. He says "I was taught to be environmentally friendly."

經濟學家上完後洗手，可是只用一張擦手紙。他說：「我受的教育是要對環境友善。」 

The teacher gets done and leaves without washing his hands. He says "I was taught not to piss on my hands."

教師上完後離開，根本不洗手。他說：「我受的教育是不要尿到自己手上。」
