A joke to ease some stress

A Civics teacher was instructing a class when he went on a tangent about languages and about people who speak multiple languages.

He asked the question, ""If a person can speak in three languages what are they called?

A student answered, trilingual

He said, "Okay, If a person can speak in two different languages what are they called?"

Another student answered, bilingual.

He said, "Correct, If a person can speak one language what are they called?"

A voice in the back of the room answered, an American.
