Either you're out or urine

Nick and I spent most of today helping our friends clean and work on the house they just bought. The previous occupants left the house more than a little dirty. The fridge was pretty gross, but the worst (by far) was the bathroom. Nick and I agree that it was the most disgusting toilet we've come across yet (and we've seen more than a couple.) We had to take it apart to even get it close to clean (removing the bolt covers and toilet seat.) We used the kind of toilet cleaner that has hydrochloric acid in it. It still took a lot of scrubbing. We feel that if we ever needed a favor from this couple, we could probably feel very comfortable calling them. The bathroom still smells. We're working on it.
