Catching fish

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 fishmongers and ordered four bream.

He told the fishmonger,

"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 brown trout."

" Trout? Why brown trout?"

"Because your wife came in earlier today and said that if you called in to buy fish, I should tell you to get brown trout because that's what she prefers!!"
