((ooc: This post takes place after Jounouchi and Meat Puppet!Yugi play a round of Dungeon Dice Monsters - the log for which may or may not be happening, I'm not sure. Either way, the outcome is that Jounouchi received a Punishment Game and is now, for a duration of time, unable to lie or hide the truth.))
