A woman got a dent in her car and took it in to the repair shop.
一位女士把车撞了一个坑,于是就去修车。

The repairman decided to have a wee bit of fun. So he told her all she had to do was to take it home and blow in the tailpipe until the dent popped itself out.
修理工决定幽她一默。他告诉她,她只需把车开回家,然后从排气管里往车里吹气,直到凹陷处自己鼓起来。

After 15 minutes of this, a lady－one of the woman's friends came over and asked what she was doing.
这位女士如法操作了15分钟。这时,她的一位女性朋友来拜访她,并问她在做什么。

"I'm trying to pop out this dent, but it's not really working."
“我正在试着让那个坑鼓起来,但这个办法似乎并不管用。”

"Duh you have to roll up the windows first!"
“嗯……你必须先把车窗摇上去！”
