A man is driving down the road and notices a car in the ditch. He doesn't 
usually help many people so he drives on by. Then he notices that a pretty 
woman is the driver so he goes back to help. As he is hooking his truck to 
her car he says, "You know, you are the first pregnant woman I've ever 
helped out of a ditch".
"But I'm not pregnant," she says.
"Well you're not out of the ditch yet," he says.
