Jimmy: 'Hey, Mike! How's your new pet fish doing? You told me he was really something special.' Mike: 'To tell the truth, I'm really disappointed in him. The guy who sold him to me said I could teach him to sing like a bird.' Jimmy: 'What? Let me get this straight... You bought a fish because you thought you could teach him to sing like a bird?' Mike: 'Well, yeah. After all, you know, he's a parrot fish.' Jimmy: 'Now listen, Mike, while you might be able to teach a parrot to sing, you're never going to get anywhere with a parrot fish.' Mike: 'That's what you think! It just so happens this fish CAN sing. The thing is, he's terribly off-key and it's driving me crazy. Do you know how hard it is to tuna fish?'
