"Pencil Break" was the hot shit for about a year in middle school. This was right on the edge of when mechanical pencils started to replace wooden ones in school (not completely, I'm sure kids still use wooden #2s.)

It was stupid, but so many people would take turns slapping pencils together to see which ones would break. Obviously brand new pencils out of the box snap the easiest, while worn down nubs are impossible to break. The school eventually banned it and briefly flirted with banning wooden pencils after parents and teachers complained that all the really dedicated students had no writing instruments left.

Nation of geniuses over here.
