A gentleman walks into a bar and orders a couple of drinks after finishing them he says to the  barman if I show you something fantastic will you give me another drink.

The barman folds his arms and says I’m a barman there’s nothing you could show me that I haven’t already seen.
The gentleman takes a deep breath and says watch this, out of his left pocket he takes out
a little piano and a stool and then out of his right a frog. He puts the frog on the stool and the frog begins to play, everything from Mozart to popular music now days.

The Barman can hardly believe what he sees and is so amazed that he gives the man a drink.
      
The gentleman was delighted and finished his drink but he still felt thirsty so he said to the Barman listen if I show you some thing even better will you give me a bottle.
The barman was curious and thought what could possibly be better than a frog
playing Mozart.

So he took up the challenge, the gentleman reached into his back pocket and produced  a little yellow canary which he put next to the piano.

So the Frog played and the canary sang everything from opera to rock and roll and even an Elvis impersonation

The barman through up his arms and laughed I’ve never seen anything like this before and handed the man a bottle. 
Just as he is about to leave the gentleman looks around to the barman and says I feel rather bad because I wasn’t totally honest with you.

The barman is shocked and says I don’t understand. To which the gentleman replies

You see the canary really can’t sing the frog is a ventriloquist.
