Mo dancing

A man with gray hair and a purple shirt stands in a classroom, initially leaning forward with his hands outstretched, then standing upright and gesturing with his hands while facing students seated at desks. He turns and pulls a large, purple, cylindrical object from behind his back, holding it like a weapon as he faces the students. Homer Simpson stands in the doorway behind him, watching. The scene takes place in a classroom with a teacher's desk, a clock on the wall, and a blackboard.
