Sorry! I've been a bit busy! 
What about something like the Mayor has just died and there's kind of a crisis of succession. A couple of different people want the position and there's been some nasty words between the different factions and stuff. 
I also like Frozen Ectsasy's idea. 
Also, this might be a bit too serious, but we could always do something like there's an armed conflict occuring nearby and the residents of the town have to deal with it.
