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?
