Once they reach the top, they decide to have a contest. They will throw their watches off the top, run down the stairs and try to catch the watches before they hit the ground.
The first Englishman throws his watch, takes three steps and then hears his watch crash as it hits the ground.
The second Englishman throws his watch and takes only two steps when he hears his watch shatter as it hits the ground.
The third Englishman tosses his watch off the tower, jogs down the stairs, goes to a candy store, buys a snack, walks back to the tower and catches his watch.
“How on earth did you do that?” one of his friends asks him.
“My watch is 30 minutes slow” came the reply.
