A stranger asked a bartender if he would give him a free beer if he showed him something amazing. The bartender agreed, so the stranger set a hamster and two frogs on the bar. The hamster just sat there, but the two frogs performed a medley of songs from Grease. "That is amazing!" said the bartender, as he poured the stranger a beer. Meanwhile, an excited man in the bar offered the stranger $5,000 cash for the two frogs. The stranger agreed, and the excited man fled with the frogs before he could change his mind. The wide-eyed bartender said to the stranger, "Are you nuts? You could've made a fortune off those frogs!" "Those frogs will be easy to replace," said the stranger. "I'm just thankful he didn't want the hamster. It's the best ventriloquist I've ever seen."
