Gozu, or "Cow Head", is a story that captures listeners attention so much they cannot stop listening. It causes tremendous fear though and leads to continuous trembling. Their body eventually gives out and they die.

Legend has it that a schoolteacher told it on the bus to entertain bored students. The students started listening but began to get frightened and begged the teacher to stop. The teacher was too engrossed in the story and didn't stop though.

The students and bus driver began to convulse, but the teacher was blind to their convulsions. When the teacher finished telling the story, the dead bodies of the students and bus driver surrounded the teacher.
