First of all, AS most likely put The Office on air because it's a beloved show that hasn't had much exposure in the US. You know, exactly like some of the other BBC comedies they've aired (The Boosh, Darkplace, Look Around You, etc). They're doing it because they think the shows deserve to be seen by a larger audience, which is completely true.
I for one think The Office is hilarious. You don't because you obviously don't have a taste for dry humor. And the sad part is, The Office isn't even that dry, it's pretty ridiculous most of the time. But since you can't look past the dullness portrayed in the workplace setting (which actually contributes to the humor), you can't decipher what is and is not supposed to be funny about the show. Sorry, babe.
