1) I was in the kitchen one day, and heard a crash from the bathroom. Ran in to find the bathroom ceiling on the floor.
Wound up getting a new roof.
2) Got out of the shower one morning and the spouse said: (I hated it when he began a sentence like this) "I don't want to alarm you, but there's a small backup around the drain in the basement." Small meaning about 5 feet in diameter.
3) Came back from a nice vacation to find a huge branch from our neighbor's tree had crashed into our fence. Knocked the entire thing flat. So much for relaxation.
4) For some reason, birds found it easy to get into my old house. One day I came back from a trip (maybe I should just stop going on vacation), and I kept hearing these rattling noises. After some investigation, I found two sparrows nestled into the glass shades in the dining room chandelier.
Although really, nothing makes me panic and fume worse than car trouble. Nothing short of a tornado flattening my house, I guess.
