Crow Man

pages 64-65

It's generally known that if you talk to the Crow Man, he will only respond with "Hang on."  It doesn't matter what you're talking about, because he never pays attention, and you can use this to your advantage.  Just start talking about coffee futures or something equally obscure and boring, and then sneak past him after the tenth "Hang on" and you'll find his treasure trove of PBR.
