Whats the coolest non-quest "quest" you have done? *Possible Spoilers*

Last night I was in a later area of stonefall (dont remember the name of the town). I came across two tents and two female dunmer arguing over a campfire that wasnt lit. Apparently listening to them talk they complained how they couldnt light it. So I saw I could light it and did and got some quick xp. Anyone else run into something cool like that?
