Whiskey Slim

Whiskey Slim is a gnome located in the Salty Sailor Tavern in Booty Bay, in the Cape of Stranglethorn. He is affiliated with the Blackwater Raiders.

He previously gave the quest Whiskey Slim's Lost Grog, whereby he tasks players with locating his Pupellyverbos Port that he lost in the Hinterlands. By the time the Cataclysm comes around, Slim has obviously kept a tighter grip on his grog since he sells Crate of Pupellyverbos Port for another quest.

Quotes
When a player buys Crate of Pupellyverbos Port from him, he will say,

"Here's to you! Here's to me! May we never disagree.

But if we do....BLAST YOU! Here's to me."
