Pat: Hey, Chris! Hows your new pet fish doing? You told me he was really something special.

Chris: To tell you the truth, Im really disappointed in him. The guy who sold him to me said I could teach him tosing like a bird.

Pat: You bought a fish because you thought you could teach him to sing like a bird? I cant believe it!

Chris: Well, yeah. After all, hes a parrot fish.

Pat: I hate to tell you this, Chris, but while you might be able to teach a parrot bird to sing, youre never going to get anywhere with a parrot fish.

Chris: Thats what you think! He can sing all right. The thing is, he keeps singing off-key. Its driving me crazy. Do you know how hard it is to tuna fish?
