I found the same dialogue in two episodes, referencing the famous box company. I thought it was funny.

S1E11 -
Boone: A box company?
Locke: They made boxes.

S1E18 -
Hurley: A box company?
Ken: Mmhmm. They make boxes.

Did they ship anything in those boxes?? I would love to see the box to see if there is a Dharma logo on it...

I don't think we've seen one of the boxes...that would be really cool though.
