A man is driving up a steep, narrow mountain road. A  woman is driving down the same road. 

As they pass each other, the woman leans out of（把身体探出） the window and yells¹ "PIG!!"  The man immediately leans out of his window and replies,  "WITCH!!" 

They each continue on their way, and as the man rounds the next corner, he crashes into a pig in the middle of  the road. If only men would listen.
