我将讲一个可以让你笑的故事。

I'd tell a tale sure to make you smile.

当摄像机在执行它的神奇的职责时，你就要保持露齿笑，这实在是太让人难以想象了，于是，一种坚定而茫然的凝视成了常态。

The thought of holding a fixed grin as the camera performed its magical duties was too much to contemplate, and so a non-committal blank stare became the norm.

你现在是一切“脆脆”事物的代言人（包括让你咯咯笑的华德福教育，以及让你渴望猪排的素食主义）。

You're now the spokesperson for all things "crunchy"， including Waldorf education and vegetarianism.

You know, even some goes pass you on the street and you don't smile ostensibly you don't smile-- there are certain micro-muscles in your face that are moving that actually make you feel better.

即使路人与你擦身而过时，你没笑,表面上你没有笑-,但你面部的细微肌肉,会收缩，让你感觉更好。
