你出你的心灵？

One more joke which i tried to translate chinese. let's criticize it.

我再一次笑话尝试翻译中文。

老师在大街上走并看见三个小孩子。
他们喝啤酒，抽烟并打麻将。
老师惊呼：你们在做什么？！？为什么你们不去学校？
他们的头目问他：你出你的心灵？谁去上学，在五岁？

Teacher walk down the street and see three boys.
They have playing cards, drink beer and smoke.
He cried: what are you doing? Why are you not at school?
Leader of them said: are you out of your mind? who has going to school in five years old?
