When I was in the fifth grade during January, I told my friends the world was going to end soon. They asked me when it was gonna happen and I said February 30th. They believed me so I told them don't tell anyone, knowing it would spread around the school. Pretty soon, it even reached other classes. Everyone got scared and some fork even told the teacher about it. Then the teachers had to tell everyone there isn't such thing as February 30th. That little prank ended up with me in the magazine as naughtiest boy in school.
