     A man was on the side of the road hitchhiking（搭便车）on a very dark night in the middle of a

terrible rainstorm, with no cars on the road. The storm was so strong that the man could hardly see a

few feet ahead of him. Suddenly, he saw a car come towards him and stop. The man, without thinking

about it, got in the car and closed the door and only then did he realize that there was nobody behind the

steering wheel（方向盘）!

     The car started to move very slowly. The man looked at the road and saw a curve （拐弯处）

coming his way. Terrified, he started to pray, begging for his life. He had not come out of shock when,

just before the car hit the curve, a hand suddenly appeared through the window and moved the wheel.

The man, paralyzed with fear, watched how the hand appeared every time the car was drawing near a

curve. Finally, although terrified, the man managed to open the door and jump out of the spooky car.

Without looking back, the man ran through the storm all the way to the nearest town. In a state of

complete horror, the man walked into a nearby bar and asked for two glasses of Scotch whisky.

     Then, still shaking with fright, he started telling everybody in the bar about the horrible experience he

just went through in the spooky car. Everyone in the bar listened in silence and became frightened, with

hair standing on end, when they realized the man was telling the truth because he was crying and he was

certainly not drunk!

     About half an hour later, two other young men walked into the same bar and one said to the other,

"Hey, there's a stupid man who jumped into the car while we were pushing it!"
