Lahni's Ferret Wine was a goof from Greetings Adventurers, revolving around the character Lahnik "Lahni" Caplain, played by Nika Howard. The character has a dead (?) ferret around her waist like a fanny pack, which is apparently filled with Elven Wine (It was revealed in a mailbag episode that the ferret probably has a full bar in it, but only the wine is referenced episode to episode). Characters who might want (for some reason) to drink from the ferret must get on their knees and suck it from the creature's mouth. It's all pretty suggestive.
