I'm gonna change this joke to make it a little more regional.

Three blonds were in a sled this weekend on the Wynoochee. They all had lines in the water. Sure enough a game warden making a run up the river spots them and heads full speed towards them. The river is closed so he's in a hurry to do some confiscating and ticket writing.

He docks up to the blonds boat and the blonds barely move a muscle. The warden says "Do you know the rivers closed? I'm going to need to see your licenses." One of the blonds speaks up "Officer, we are looking for jewerly and odds and ends on the bottom of the river. We have magnets attached to the end of all our fishing rods." The officer says "Well, I'm going to need all three of you reel up your lines so I can see these so called magnets." Sure enough, all three blonds reel up their lines and all three have big magnets on their lines. The officer shakes his head then says "Well, you're doing nothing illegal, so have a nice day." He jumps back in his boat and heads up river to see if anyone is poaching. Just as he turns out of sight the three blonds starting laughing their asses off. The blond who originally spoke with him blurts out "That officer is such an idiot, doesn't he know there's STEELhead in this river?!?!?!"

Sorry if I offended any blonds out there.
