A guy walks into a bar. He goes up to the bartender and says, "If I can surprise you, I get a free drink." The bartender was unsure but agreed.
The guy pulled a 30cm long pianist out of his pocket, and he starts to play.
The bartender was surprised and gave the guy a free drink.
The guy then says, "You see, I have a little wizard in my pocket that grants wishes. Can I get another free drink if you get a free wish?"
The bartender agrees without hesitation.
The bartender wishes for 1000 bucks, but he gets 1000 ducks.
"WTF!" the man shouts.
The guy answered, "Did you think I wanted a 30cm long pianist?"
