A guy walks into a bar and asks the bartender if he'll give him a free beer for an amazing trick. The bartender agrees. The guy pulls out a hamster that begins dancing and singing. That is amazing! says the bartender and gives him a beer. If I show you something else, will you give me another beer? The bartender agrees.The guy pulls out a small piano and a frog. The same hamster plays the piano while the frog dances and sings.The bartender, completely wowed, gives him another beer.A man in a suit, who's been watching the entire time, offers to buy the frog for a large sum, and the man agrees. Are you nuts? asks the bartender. You could've made a fortune off that frog. Can you keep a secret? asks the man. The hamster's a ventriloquist.
