6.0 Pre-Patch added Secretive Whistle, a rogue proprietary item. Rogue can steal the Secretive Whistle from NPC when against Orc invasion in Blasted Lands Nethergarde.
Use Secretive Whistle summoning a merchant to trade with you. In other words, you can exchange some Dingy Iron Coins from Griftah with items that stolen from humanoid. How much Dingy Iron Coins you can get is decided by the rarity of the item. Dingy Iron Coins is a rogue-only currency used to gain items and gold. Like Sinister Rogue Mask, Barrel of Bandanas and Illusion: Poisoned - Rogue from Griftah.
If you already have these Rogue exclusive items, Griftah will also offer you some Weekly Quests. You can finish the weekly quests by Dingy Iron Coins to reward WoW gold from Griftah. 
Comparing with the stolen Deep Fried Plantains, Secretive Whistle is a kind of welfare for rogues. With the unique Rogue Mask and toys, Pickpocket finally has its unique meaning.
