Four Catfish

Jim had an awful day fishing on the lake, sitting in the blazing sun all day without catching a single one. On his way home, he stopped at the supermarket and ordered four catfish. He told the fish salesman:

- Pick four large ones out and throw them at me, will you?

- Why do you want me to throw them at you?

- Because I want to tell my wife that I caught them.

- Okay, but I suggest that you take the orange roughy.

- But why?

- Because your wife came in earlier today and said that if you came by, I should tell you to take orange roughy. She prefers that for supper tonight.
