A drunk walked into a tavern, sat down at the bar. He placed a small cardboard box on the bar, and ordered a beer. When the beer came, he opened the box, pulled out a tiny piano and bench and set them on the bar, then ordered another beer. When the beer came, he reached into the box, pulled out a frog, sat him on the piano bench and said, „PLAY“. The frog immediately began to play the piano. It played all the favorites, and some classical and then launched into contemporary jazz. The man ordered another beer, and when it came he reached into the cardboard box and pulled out a little white mouse. He set this mouse on top of the piano and said „SING“. The frog began to play the piano and the mouse began to sing, first some ‚oldies but goodies‘, then all of the current favorites.A man at the bar who was watching all of this approached the drunk man and offered to buy this little outfit that he had. After a bit of negotiating, the drunk man agreed to sell it to the man for $500. The man gathered everything into the little cardboard box and ran out the door before the drunk could change his mind.The bartender had been watching all of this goings on and said to the drunk „You damned old fool! You just sold that little outfit you had for $500 and you could have made millions off of it!“ The drunk laughed heartily and replied „I am not the fool, the guy who bought it is. Do you really think I would have sold that if that mouse could really sing?“The bartender responded „What do you mean, I stood right here and listened to that mouse sing!“ „The joke is on you and the guy who bought that outfit my friend“, chuckled the drunk. „That mouse can’t sing. The frog is a ventriloquist!“
