Asian scientist: What is in the box?
Shipping clerk: I don’t know, but it’s probably cells, since it says ‘dry ice.’
Asian scientist: But what’s in the box?

Asian scientist: Okay, but what’s in the box?
American scientist: I think that’s the stuff you ordered.
Asian scientist: Oh, yes, okay. But what can possibly be in the box?
