What did the fish say when he swam into a concrete wall?

Dam!

Game warden: Didn’t you see the no-fishing sign, son?
Boy: I’m not fishing, sir. I’m teaching these worms how to swim!

Two guys are fishing and one of them catches a huge 10 pound Walleye. They get the trophy in the boat and the fish looks up and says “If you release me, I’ll grant you a wish”. The first guy says “Great! I wish the whole lake was full of ice cold beer”. The Walleye says “Done!” and they put her back. The second guy says disgustedly “Well you sure messed that up. Now we have to pee in the boat!”

What’s the difference between a (money grubbing outdoor heritage stealing) Minnesota State Legislator and a Bullhead?

One is slimy, has whiskers, and stinks.

The other one is a fish.

Older guy has been rumored to have been using dynamite to catch his fish. DNR are on to him, but need to catch him. One day, the warden spots him heading through the trees to a pond with a rod and tackle box. Warden smiles knowing he is about to catch him.

He follows the guy to the pond and waits, but the guy is just staring at the water. So he decides to confront the older gentleman. 

He introduces himself and says that he knows he’s been using dynamite to fish, and that it’s illegal. The older guy acknowledges that it’s illegal, than says “hold on a second”. He reaches into his tackle box, and lights a stick of dynamite. Turns around and hands it to the warden, and says “Well, are you gonna stand there, or are you gonna fish?!”
