The businessman's accident
Joke:What is a joke?
One day in New York City, a banker was driving his new Jaguar down the streets. He parked it and opened the door to get out. Suddenly a taxi went by, hit the door of the car and pulled it off. The driver reported this to a nearby police officer. The officer saw the whole thing and said "You bankers are so involved in your possessions. You didn't even notice that your arm was ripped off as well" The banker stared at where his arm used to be and said "OH NO! My new rolex is gone too!"
A Jaguar is a type of car.
If your arm is ripped off, it comes away from your shoulder.
A rolex is a very expensive type of watch.
