Pat: Hey, Chris! How’s your new pet fish doing? You told me he was really something special.
Chris: To tell you 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.
Pat: You bought a fish because you thought you could teach him to sing like a bird? I can’t believe it!
Chris: Well, yeah. After all, he’s a parrot fish.
Pat: I hate to tell you this, Chris, but while you might be able to teach a parrot bird to sing, you’re never going to get anywhere with a parrot fish.
Chris: That’s what you think! He can sing all right. The thing is, he keeps singing off-key. It’s driving me crazy. Do you know how hard it is to tuna fish?
