也很遗憾告诉你有语法错误.
首先,这篇文章是叙述过去的事情,除了对话里的内容,其他均要用过去时态的.所以修改如下：
Four best friends met at the hospital since（用when比较合适点） their wives were giving births to their babies.The nurse comes（came） up to the first man and says（said）,"Congratulations,you got twins." The man said "How strange,（用感叹号啦~） I'm the manager of Minnesota Twins." After a while the nurse comes（came） up to the second man and says（said）,"Congratulations,you got triplets." Man was like "Hmmm,strange I worked as a director for the "3 musketeers." Finally,the nurse comes(came) up to the third man and says (said)
"Congratulations,you got twins x2." Man is(was) happy and says(said),"Ironic,I work for the hotel "4 Seasons." All three of them are(were) happy until they see(saw) their last buddy jumping all over the place,cursing God and banging his head on the wall.They asked him what's wrong (what was wrong/ what had happened)and he answered,"What's wrong?I work for 7up"!
