A dumb blonde is walking along, lost, and encounters a deep and wide river.
She looks up and down the river for a way across, but is unsuccessful in finding one.
Yet, when looking to the other side, she sees another blonde on the opposite river bank.
She calls out to her, “Hey, how can I get to the other side of the river?”
The other blonde looks over and shouts back, “What for? You’re already on the other side!”
