Only one man

No one in this town could catch any fish except this one man.

The game warden asked him how he did it so the man told the game warden that he would take him fishing the next day...

Once they got to the middle of the lake the man took out a stick of dynamite, lit it, and threw it in the water. After the explosion fish started floating to the top of the water. The man took out a net and started picking up the fish.

The game warden told him that this was illegal. The man took out another stick of dynamite and lit it. He then handed it to the game warden and said " are you going to fish or talk?"
