A man goes into a bar and asks the bartender, “If I show you the most amazing thing you’ve ever seen will you let me drink for free tonight?” The bartender says, “Let me see and I’ll consider it.”
So the man reaches into his bag and pulls out a miniature piano and a hamster. The hamster sits in front of the piano and starts playing, and not just chopsticks but Chopin, some ragtime and even some rock’n’roll.
After a few minutes the bartender says “Okay, I’m impressed, you can drink for free.” As the bartender is pouring the man a drink the man says, “Hey, if I show you something even more amazing will you let me drink for free for a month?”
The bartender says, “Okay, but this had better be spectacular.” So the man reaches into his bag and pulls out a microphone and a frog. The frog sits in front of the microphone and begins singing along with the hamster playing the piano.
The bartender says, “Okay, you can drink here for free for a month.”
Another customer at the end of the bar has been watching. He walks over and says, “I’m a theater producer and I’d like to buy that frog and put him in a show. Will you sell it to me for $500?” The man says no, so the producer offers to buy the frog for $5000, and the man agrees.
As the producer leaves with the frog the bartender says, “I can’t believe you sold the frog! It was worth more.” “Not really” the man says, “The hamster is a ventriloquist.”
