Upon further review, it actually was this and not "West I'm Breakin' Up With You" as I previously thought. And now that I think about it, even it was that, I still wouldn't get it.
You're not getting off at the Homestar station anymore! You're riding the 7:30 Alone Train to Alones-ville! With stops at Ex-Girlfriend Junction and West Breakin' Up With You!
