I hate it when that happens. I know it's a necessity but I still don't have to be happy about it.
Luckily I live in a market where that rarely ever happens. By my count, it's been exactly once, and the situation only arose because of Election Day (the episode was moved to Saturday) and a college football game ran long (I know Michigan was involved). IIRC each subsequent time the power hour was preempted for sports, they simply aired it at a later time.
Now, if the Knicks ever make it to the Finals again, I could potentially be singing a different tune.
