It is a common thing for me to have a spontaneous realization about music lyrics.
I might be in the shower. I might be driving to work. Without any clear motivation I'll think of a music lyric, followed by the thought of "oh!!!! that's what that means!" It happens with rap a lot, sometimes lyrics I've known for 20 years.

I've always been familiar with the "Hollywood" song. I'm not any particular fan of it or anything.
You know the one... Hollywood... da-da-da-da-da-da-da-da Hollywood...
Although I'm familiar with it, I know few of the lyrics. One that I've always (since I can remember, really) had in my head is "From Shirley Temple to Aimee Semple..."
I've always just sort of assumed I didn't really know that 2nd name or I remembered it wrong, since Aimee Semple isn't anyone I was familiar with. I've never been interested enough to look it up.
Aimee Semple is of course Sister Aimee McPherson, a totally fascinating person I learned more about a couple of years ago with this KCET article.
The sort of funny thing here is that I never connected those names until about five minutes ago.
It's 6:30 AM on a Saturday. I just woke up, got out of bed, picked up the already-filled laundry bag by the door, and exited my apartment to walk to the laundry room on the other side of the building. As I approached the laundry room, my eyes still gooey and gross (they still are), it all of a sudden hit me. "Aimee Semple!!! Aimee Semple McPherson!" Totally out of nowhere. So stupid and weird.
