Xxxdarknessxxx; This song has to do with someone loving a certain person, but the person's already taken. And with the, "Darling, I know what you're going through" part, it's the someone talking to the person about a problem that the person has. Maybe unhappiness, or something. "The last time you came through", the someone's probably talking to the person about how her husband, or boyfriend got mad at her because he thinks she's cheating, and show she got through the fights.
But, over-all, this song talks about a love triangle, basically.
And the song title. They never really do relate to the song, as it seems, but the title itself makes perfect sense if you're a baseball fan. Cooperstown in a place in New York, possibly where baseball originated, and there was a baseball player who, on home-runs, had a popular thing of diving headfirst onto home base after the run was done. The bad bet part had something to do with the baseball players career, I believe. By the way, the only reason I got this assumption was because we had to look up and do a one-page report on a certain sport in school, and during my research, I read about the whole thing. Then, as I was reading, I began to piece together how the title would make sense, and I ended up with that.
So, yeah. You have to think about most things having to do with any of fob's songs or titles before you fully understand them. That's what I love about fob's music. They always make it interesting, and I hate it when thinks are so apparent. ;]
