A mangy-lookin' guy goes into a bar and orders a drink. The bartender says, 'No way. I don't think you can pay for it.' The guy says, 'You're right. I don't have any money, but if I show you something you haven't seen before, will you give me a drink?' The bartender says, 'Only if what you show me ain't risque.'
'Deal!' says the guy, pulling out a hamster from his coat pocket. Once he sets the hamster on the bar, it dashes off, climbing over a barstool before racing across the room to the piano. It then leaps up on the keyboard and begins to play Gershwin tunes. The hamster, too, is top-notch. The bartender responds, 'You're right. That is the first time I have ever seen anything like it. That hamster plays the piano beautifully. The guy finishes his drink and requests another from the bartender. 'Money or another miracle, else no drink,' says the bartender.
The guy reaches into his coat again and pulls out a frog. He puts the frog on the bar, and the frog starts to sing. He has a marvelous voice and great pitch and is a fine singer. A stranger from the other end of the bar runs over to the guy and offers him $300 for the frog. The guy says, 'It's a deal.' He takes the three hundred and gives the frog to the stranger, who runs out of the bar with it.
The bartender says to the guy, 'Are you some kind of nut?! Did you sell a singing frog for $300? It must have been worth millions. You must be crazy!'
'Not so,' says the guy. 'The hamster is also a ventriloquist!'
