A man in a blue hat walks into a bar, sits down at the bar, and orders a drink. After a while he turns to the fellas sitting next to him and says "Hey, fellas, I'll make you a deal: If I can show you the most amazing thing you've ever seen, something you have never seen before, you will each pay me 20 bucks. But, if you don't think it's the most amazing thing you've ever seen then I'll pay each of you 20 bucks."
The guys have a wee chuckle but agree. They sit and watch with curious smirks as the man with the blue hat pulls a small man, less than a foot tall, from the bag he has on the floor beside. He also pulls out a small piano and stool. He puts the piano on the bar and the tiny man sits down at begins to play the most beautiful rendition of Beethoven's Moonlight Sonata the men have ever heard.
After he has finished and they have all applauded, the fellas take out their wallets and each give the man in the blue hat 20 bucks, admitting it was indeed the most amazing thing they had ever seen.
As the man in the blue hat puts his money away and goes back to drinking, one of the fellas approaches him and asks where he found the small guy. "I actually got him from a genie," replies the man in the blue hat and pulls a lamp out of his bag.
"Wow!" exclaims the other fella and proceeds to ask if the genie is still in there. After the man in the blue hat nods, the fella asks him if he might also ask the genie for a wish. "Sure," replies the man in the blue hat, "but he will grant each person only one wish."
The other fella rubs the lamp and out comes the genie in a puff of smoke. The genie booms "I WILL GRANT YOU ONE WISH."
The fella thinks for a second before telling the genie "I wish for a million bucks!" "GRANTED!" exclaims the genie before disappearing back into the lamp. The guy looks around, puzzled, as he doesn't see the money anywhere. Then they hear the sound of quacking rapidly getting louder. All of sudden, ducks start pouring into the bar through the doors and windows.
"What's going on?" the fella asks the man in the blue hat. "Oh, I forgot to mention," the man in blue hat replies, "that the genie is a tad hard of hearing. Do you really think I wished for a 10 inch pianist?"
