Two blondes were running from the cops as they had just been caught sneeking over the border into Mexico. They dashed up to a fence and climbed over it, lights and sirens running behind them. As they arrived on the other side, they came face to face with a long river. One blonde said to the other. "Here I'll shine this flashlight over the water and you can walk accross the beam of light." The other said: "What do you think I am, stupid!? I'll get halfway accross and you'll turn it off!"
