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."
