yeah, but that's a single quest, and it's not even that fun, just go here, click on thid, dteal this and come back, TADA.

The Grey-Mane's have the one at to free Thorald from Northwatch, then Eorland is involved in the Companions, and if you're Stormcloak aligned(Which I almost always am) Vignar becomes Jarl, which in of itself can lead to them being involved in the Main Questline.
