A homeless man walks in to a bar carrying a briefcase. He takes a seat at the bar and calls the bartender. "Say, what would you give me if I could make a frog play your piano?" he asks pointing to the baby grand in the corner.

"Well I'd give you a drink - on the house," says the bartender with a smirk, certain that the bum is full of it. The bum shrugs, walks over to the piano and opens his briefcase. Out of the briefcase hops a frog. It lands on the piano and begins to play the most exquisite classical music the bartender had ever heard. Amazed at the sight he pours the man a drink.

"What would you give me if I could make a rat sing?" asks the hobo, half-way through his drink.

"Buddy, I'd give you free drinks for the rest of the night!" The bum nods, walks over to the piano and reaches in to his briefcase. Out he pulls a rat which he sits next to the frog. The rat proceeds to sing the most beautiful aria the bartender had ever heard.

Completely blown away by the performance, the bartender serves the bum another drink. He is taking a sip when a finely-dressed businessman approaches him.

"That's quite an act you got there," he says, "I'll give you a million dollars for it."

"It's not for sale," replies the bum.

"Ok, well then how about $500,000 for the rat?" he bargains.

"Deal," says the bum. The businessman pulls his checkbook out of his coat pocket and writes the bum a check. He then grabs the rat, shakes the bum's hand and leaves.

"What are you doing?" asked the bartender. "That was a multi-million dollar act you had there!"

"Don't worry," said the bum. "The frog is a ventriloquist."
