Three blondes are sitting by the side of a river holding fishing poles with the lines in the water. A Game Warden comes up behind them, taps them on the shoulder and says, "Excuse me, ladies, I'd like to see your fishing licenses." "We don't have any." replied the first blonde. "Well, if your going to fish, you need fishing licenses." said the Game Warden. "But officer," replied the second blonde,"we aren't fishing. All we have are magnets at the end of our lines and we're collecting debris off the ottom of the river."
