Trivia: Jerry Siegel, the co-creator of the Clark Kent/Superman character worked on a school magazine when he was at Glenville High School, Cleveland. The magazine was called The Torch - the same name of Smallville High's school magazine, edited by Chloe Sullivan and with Clark Kent as an on/off contributor.
