Chrome stronger than iron

Ride four students on the old six. They stop at a traffic light. A powerful blow in the trunk. Turn around - is heaped up behind the Jeep. Students sit in the car and realize that got out of the jeep ... nehily couple of kids, consider kangaroo trunk ... a few minutes later, the jeep drove to the door of the driver, that neither alive nor dead, knocking on the window, said: "Open."
Do nothing, he reveals. Kid:
 - How much is your car worth?
Student:
 -?! Well ... thirty thousand ...
Kid counting the money, turns, goes to the car and on the way said to his companion:
 - I told you that chromium is stronger iron.
Students shock.
