I just wanted to ask, been bothering me lately. I know it isn't much and this is probably useless question by some but, when you walk past guard and he says; "What is wrong? Dragons?" I always wonder is he sarcastic or just dumb.
Yes, sweetroll joke is well known, showing us basicly that even guards have sense of sarcasm and humor, so I am really wondering, is this the case as well? What do you think?

An epic response...

GUARD: "What's wrong? Dragons?"

DRAGONBORN: "OH DA VIING!!!!!!!"

Odahviing flies down, chomps the guard, eats him in a few messy gulps.

DRAGONBORN: "Yup."

"What is it? Dragons?"

Well thicko I think that you'd be able to hear and see a dragon a mile away but hey I'll keep an eye out for you >_>.

Its like if you bumped itno a cop and he/she asked "What is it? Terrorists?"

I like that line, a lot.

Some of the guards are on-edge about dragons. It makes sense, but it's funny too.

They're nervous. Same with "Watch the skies, traveler".
