Clean jokes-Throwing watches

There are four tourists from India who are visiting London. They go to see the Big Ben. They all climb up the tower and decide to throw their wrist watches from the top, then hurry down the stairs and try to catch them before they hit the ground.

The first tourist, Amar, threw his watch but heard it crash before the had taken four steps.

The second tourist, Vinod, threw his watch and had hardly taken three before when he heard his watch shatter.

The third tourist, Harry, threw his watch and by the time he had taken two steps, the watch hit the ground.

The fourth tourist, Santa Singh, threw his watch off the tower, went down the stairs, bought a cup of coffee from a shop down the street and walked slowly back to Big Ben in time to catch the watch.

"How on earth did you do that?" asked all his friends.

"Simple", Santa Singh replied, "My watch is slow by 30 minutes."
