笑话原文】
Visiting a Chicken Farm
One day, a teacher took his pupils to a chicken farm to pay a visit.
When they came near the incubator, a chick just got out of its eggshell.
“It’s wonderful to see a little thing come out from the eggshell, isn’t it?” the teacher said.
“Yes, sir.”said one of the boys, “but it would be more wonderful if we know that how a chick gets into its eggshell beforehand.”

当他们来到孵化基地旁边时，一只小鸡正好破壳而出。
