Cipher of the Goblin deep
The Goblin Annual Review's special issue on deep has, by tradition, been printed exclusively on the backs of stolen restaurant menus.
An obscure goblin festival celebrates the day deep was first noticed by the goblin community at large. Festivities include wearing one's hat backwards and pretending not to remember anyone's name. The festival lasts exactly as long as participants can stand it.

The goblin closing argument on deep consists of pointing at deep, then pointing at the audience, then sitting back down. Goblin juries find this persuasive.
