A teacher or other instructor throws chalk pieces (or other small objects) at their distracted pupils. Often the scene will first focus on one or two students not following the class, before an unidentified object flies towards them and gets their attention back to an irritated teacher.
This is usually Played for Laughs, and the chalk will be thrown with uncanny accuracy at the kids' heads, showing that the teacher has a long "experience" in this domain. The Badass Teacher and Sadist Teacher will often use this technique as a way to quell troublemakers; the Stern Teacher also occasionally gets in on it.
- Tommy Lee Jones has appeared in commercials for a Boss Coffee where he's an alien teaching Japanese students.
