Bob was fishing a stream but not catching anything. He decided to get up and move downstream to see if his luck would change. He came upon a man fighting a nice bass. After the fish was landed, Bob asked, " Wow! What are you using for bait?"

The man said, "Well, I'm a surgeon, and if you promise not to tell, I'm using an appendix I took out yesterday."

Bob said, " An appendix? Does it work?"

The surgeon replied, "Look at this," and lifted a full stringer out of the water. "This one makes my limit."

Bob leaves and goes downstream further. He sees another man landing a large one too. Bob asks, "What did you catch it with?"

The man said, "Actually, if you promise not to tell, I'm a plastic surgeon and I'm using a bit of nose I clipped off a woman."

Bob is aghast that human flesh is working so well on these fish, as he is shown another full stringer. Bob leaves and walks further downstream. He comes upon another man with his rod bent almost double with a large one.

Bob says, "Let me guess. You're a surgeon too."

"No," says the man. "I'm a rabbi."
