Be Nice

Ne nice or you won't get to go the heaven when you die and be with your mommy and daddy for all eternity, and Satan will drag you down to the depths of Hell and you'll burn forever in a pit of fire, and Satan's demons will poke you with pitchforks and laugh at you for being a foolish boy and, no only that, but your sons and their sons and their sons will burn in the pits of fire too.
