The Hamster Show
A guy walks into a bar and asks the bartender if he will give him a free beer if he shows him something amazing. The bartender agrees, so the guys pulls out a hamster, who begins dancing and singing “Tuff Enuff” by the Fabulous Thunderbirds.
“That IS amazing!” says the bartender and gives the guy his free beer.
“If I show you something else amazing, will you give me another beer?” The bartender agrees, so the guy pulls out a small piano and a hamster and a frog. Now the hamster plays the piano while the frog dances and sings “You Ain’t Seen Nothing Yet” by Bachman-Turner Overdrive.
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 princely sum, which the man agrees to.
“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.”
