Word/Song Association

I have a "do you do this too, or am I weird*" question for you. This morning I was looking through my FB memories, something I do most days, and then realized I had this running through my head, from the movie version of Buffy the Vampire Slayer.
*Granted, I am weird in a lot of ways, but is this one of them?

Okay then, but why? It certainly wasn't one of the items in that list. I looked back at what I had scrolled past, and there it was:

So the word "caboose" went by, and my brain decided to do word-association games without me even realizing it.

Mind you, Buffy isn't even a movie I've seen many times. But I've probably mentioned before how strongly music helps something stick in my mind (Schoolhouse Rock, anyone? who else can sing the Preamble to the Constitution with me?). I would expect it more of a favorite movie, I guess. I mean, just the other day I was quoting from The Philadelphia Story in our work chat. I could probably recite more than half the movie along with the actors, so it was no surprise when this came to mind on a bad morning:

And this morning, after thinking about these two things, I realized I had "Lydia the Tattooed Lady" running through my head, because of course I did.

(I had most of the song right, too. Dinah Lord is a lot of fun in that movie.)

So, do you do this? Find a song stuck in your head because of a random word you barely noticed? Because this happens to me all the time.

Follow-up question: When you get an earworm, does it wear off, or do you need to "write over it" by playing a different song? For me, sometimes it goes away, but if it doesn't, I will reprogram, either with a recent favorite, or my classic, Clean by Depeche Mode.
