Three blondes are sitting by the side of a river holding fishing poles with lines in the water. A game warden comes up behind them and says, “Excuse me, ladies, I’d like to see your fishing licences.”
“But officer,” replied one blonde, “we aren’t fishing. We all have magnets at the end of our lines and were collecting debris off the bottom of the river.”
The game warden lifted up all the lines and, sure enough, there were horseshoe magnets tied on the end of each line.
“Well, I know of no law against it. Take all the debris you want.” Then he left.
As soon as he was out of sight, the three blondes started laughing.
“What a stupid fish cop!” The one blonde said to the others, “Doesn’t he know that there are steelhead trout in this river?!”
