Why would anyone want to ruin a perfectly good Game Boy like that?
The Houston Chronicle is reporting that a high school student hollowed out a Game Boy, filled it with gunpowder, brought it to school, and then talked to his friends about it, which eventually led to the police picking up the story. The boy was taken into custody and the bomb was neutralized.
There was no word on which game the system had in it at the time, but we're willing to wager that one of the Bomberman games was inserted.
