Joke: Teacher

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." The economist gets done, washes his hands, but uses only one paper towel. He says "I was taught to be environmentally friendly." The teacher gets done and leaves without washing his hands. He says "I was taught not to piss on my hands."
