We may be on to a whole new era in criminal rehabilitation here. Howsabout sending Gamecubes with Animal Crossing, SMS and Pikmin to maximum security penitentiaries across the country? Obviously painting all the cell blocks in pastel colors hasn't made them any gentler (although I imagine it sets a bit of a romantic mood for can-rapeing your new cellmate).
Well, lets scratch SMS from the list. If those frustrating red coin levels disturbed MY mellow, imagine what they would do to a 300 lb sociopath with anger management issues.
