Don't have time for either breadth or depth, just this.
Our church held an Easter Sunrise Service in a park near the church building. Everything went nicely, except....
When the pastor started preaching, this nearby dog started periodically screamyelpbarkhowling. It wasn't exactly a bark, a yelp, a howl; it was the most distracting it could be.
And it kept it up through the whole sermon. Soon as he stopped, it stopped.
Didn't do it through the singing, the reading, the very brief announcements. Just the sermon.
