A man walks into a bar and tells the bartender he’s got something amazing to show him.
From his coat pocket he pulls out a tiny piano and chair. From another pocket he brings out a little mouse. From a third pocket he lifts out a butterfly and sits it on top of the piano.
Then the mouse started to play the piano and the butterfly sang a Cole Porter medley. The bartender is truly amazed, but the man looks uncomfortable. He pockets his little act and starts to leave but turns back at the door.
“Look,” said the man, “there’s something I have to confess. This act isn’t as amazing as you thought.”
“Oh, a hoax, eh?” says the bartender.
“In a way,” the man admits.
“The truth is that butterfly can’t sing at all. The mouse is a ventriloquist.”
