THE MURREN MOORS
This is a Tunnels and Trolls adventure in the Castle Calahony series.
You quickly become friends with captain Just, chief of the castle guards.
He bores you with a joke:
A wizard walks in to a bar and orders a drink. The bartender serves him, but the mage has no money to pay for the drink. Before he could be kicked out, he says to the bartender: "Listen, I've got something that's guaranteed to entertain your patrons all night, and I'll show you if you give me another free drink."
The bartender decides to give the guy a chance. The wizard pulls a tiny piano out of his coat, and places it on the bar. He then takes a tiny little guy, about a foot high, out of his coat, and sits him down in front of the piano. The little guy starts playing the piano, and sure enough, the customers are enthralled the entire time he's playing.
After the bar closes for the night, the bartender asks the mage where he got the piano and player. The wizard says: "Give me one more drink, and I'll show you."
So the drink is served, and the wizard takes a lamp out of his coat. "I rubbed this lamp and made a wish." He hands it over to the bartender, and tells him to rub the lamp and make a wish. The bartender does this and.... POOF!!! The bar is filled with ducks! Ducks everywhere! There's no getting away from all these ducks!
The bartender's furious! He yells: "What are all these ducks doing here? I didn't wish for ducks! I wished for a MILLION BUCKS!".
To which the mage replies: "Do you honestly think I wished for a twelve inch pianist?"
Bored, go to bed.
