A man walked into a bar. He sat down and asked the bartender "If I impress you, can I have a free drink?" The bartender said sure, so the man reached in his pocket and pulled out a tiny piano. He then pulled out a small rat and set it by the piano. It crawled on to the bench and began playing
The bartender was amazed, so he gave the man a beer. Next, the man said, "If I impress you even more, can I have free drinks for life?" The bartender didn't think it was possible, so he agreed. The man pulled a frog out of his pocket, and it began to sing by the piano.
The bartender smiled and told the man that he was impressed. A man in a suit with a cane walked into the bar, saw the small animals, and offered to buy them for $2 million. The owner said no, but he offered to sell the frog for $500k. The rich man agreed, took the frog, and left. The bartender couldn't believe the owner just did that and said "Why did you just sell the frog?! There is no singer now!"
The owner laughed and said, "Don't worry, the rat is a ventriloquist."
