In the lead up to the release of Episode 1, the Sci-Fi channel ran some bumpers of fans waiting in line arguing with each other. One of them said something to the effect of, "Given that this is a prequel, and that we know the universe is expanding, shouldn't the crawler read, 'A slightly less long time ago in a Galaxy slight less far away...'" 25 years later and that still pops into my head sometimes.

That really depends on what you count as a Galaxy. If any cluster of stars that is gravitationally bound together counts, then there is a tiny (10,000 stars) galaxy that is orbiting The Milky Way that's only about 10,000 light years away from us, which happens to be closer than the center of our own galaxy.
What will really bake your noodle is that it takes time for light to reach us. We are seeing light that anywhere from a few minutes to a few billion years old.
