Joke of the day

This morning, my boss M who sits just next to me, asks me:"X, how does 笑口榛子 taste?", his fingures pointing to the nuts pot on my table, which is a gift brought from china, from my friend.

Me: Huhh?????? He reads Chinese??...

He is famous of "knowing everything" and my team has a common saying "Ask M! " when we need to know anything random.
He knows Maths, of course and he's genius in computer science, he knows everything we need for this profession and he knows lots of other science and tricks, plus 3 languages...
And now, he speaks Chinese, too?? ...........??

Then I looked back on the pot, and laughed to death.
