Read the passage.

People were always telling Jimmy to settle down and keep quiet, especially his teachers. Jimmy emerged as the chief disruptive force in his classes. As soon as he came into view, teachers knew that chaos would follow. If someone made a mistake, Jimmy was the first to notice and point it out. If someone got an answer right, Jimmy would make fun of the student for trying too hard. The joking and insults were a constant interruption and came at frequent intervals.

Trips to the principal’s office and detentions didn’t curb his outbursts. Jimmy’s father even tried to get him to back off by threatening to send him to a military academy. For a while, it seemed, nothing could make Jimmy retreat from his bad behavior. What no one knew was that Jimmy thought he was practicing for a future career as a stand-up comedian.
