I fast traveled to one of those farms just outside Whiterun, and suddenly I heard a dragon attack from just above me and ran for cover in that guard tower (this was not the first dragon, but a later one).
Just as I fled past a Whiterun guard in the doorway he starts talking to me, that old line about how bored he is about just dealing with bandits, and if only they had some dragons to fight.
That made me smile.

Oh, and all those nords saying they might be Dragonborn. Silly, silly them.
