Somebody that you used to know

I know that everyone and their mother has heard this song by now (or at least that's what it seems like via my Facebook newsfeed).

This song gets stuck in my head. I think I muttered it under my breath the entire day today. I really ought to download it on iTunes so I don't have to hunt down the YouTube version...but on the other hand, I quite enjoy the music video.

Of course, this song reminds me of people from the past.  (I wonder whatever happened to my boyfriend from kindergarten...?)
