This happened about five years ago, but I still kind of crack up about the absurdity of the stiuation.  There's some swearing involved, just to warn people.  I lived next to a baptist church in a not so nice part of town for a couple of years.  There were about five of us living in the house and we had a really long driveway, so parking was sometimes difficult since we crammed five cars into this driveway.  Anyway, I come home one day from the laundromat and can't pull in because there is an old school cadillac parked in the driveway.  Kind of annoying, but no big deal.  I just figured that one of the housemates had a friend over.  So, I get inside and my one housemate Matt tells me the car actually belongs to a woman who went into the church and had been in there for over an hour.  He's really pissed because he needed to leave and was going to be late for work.  So, the lady finally comes out of the church, all decked out in her Sunday best with a little kid in tow.  Matt leans out the window (we were on the second floor) and says, very nicely, "excuse me m'am, but could you move your car?  You're blocking me in and I really need to get to work."  The woman turns around and starts screaming at the top of her lungs "Why don't you come down here and make me move, mother fucker.  I'll kill you and your mother fucking friends and burn down your house while your sleeping, mother fucking bleep bleep bleep."  I won't even repeat some of the things she said.  I finally had to put my two cents in and told her she wasn't being very christian and she called me a stupid twat and told me she was going to kill me.  She started kicking the house too.   I swear I'll never forget it because I was so stunned at her explosive response to a very nice and reasonable request.
