      A Scotsman and an Englishman lived next door to each other. The Scotsman owned a hen and each

morning he would look in his garden and pick up his hen's egg for breakfast. One morning he looked into

his garden and saw that the hen had laid an egg in the Englishman's garden.

      He was about to go next door when he saw the English-man pick up the egg. The Scotsman ran up

to the English-man and told him that the egg belonged to him because he owned the hen. The Englishman

disagreed because the egg was on his property (财产).

     They argued for a while until finally the Scotsman said, "In my family we normally settle disputes (争

议) by the following actions: We kick each other and we compare the time how long it takes us to get

back up. Whoever gets up quicker wins the egg."

     The Englishman agreed to this, so the Scotsman found his heaviest pair of boots (皮靴) and put them

on. He took a few steps back, then ran toward the Englishman and kicked as hard as he could in his

stomach.

     The Englishman fell to the floor, holding his stomach and howling (嚎叫) in pain for 10 minutes.

Eventually (最终) the English-man stood up and said, "Now it's my turn to kick you." At this time, the

Scotsman said, "oh, maybe you should just keep the egg."
