實(shí)用口語(yǔ):如何說(shuō)"笑掉大牙"

"真是讓人笑掉大牙啊。"這是一句很簡(jiǎn)單的話，來(lái)看看你會(huì)不會(huì)犯中國(guó)式英語(yǔ)的錯(cuò)誤吧。用英語(yǔ)應(yīng)該怎么說(shuō)呢？
    【英文對(duì)比翻譯】
    Chinese Style -- That really makes people laugh off their front teeth.
    American Style -- That really makes people laugh off their head.
    點(diǎn)評(píng)：
    “笑掉頭”可比“笑掉門牙”更嚴(yán)重，看來(lái)英國(guó)人比我們還夸張。
