If You're Gonna What?!?!

BeyoncĂ©’s “single ladies” has been getting a lot of airplay around here lately. I suspect that’s at least in part because once the broadcast mega-corps discover that people like a certain song, they feel obliged to play it into the ground. But I don’t begrudge BeyoncĂ© her success, I’m certain she deserves it.
The only problem is, I keep mishearing that song. Perhaps it’s the acoustics of the room my radio is in; perhaps it’s my hearing; or perhaps it’s simply my preference for songs with a tempo I can dance to. Whatever the reason, I can’t quite make out some of the lyrics.
According to a quick Google search, the lyric is supposed to be, “If you liked it then you shoulda put a ring on it.” The ex-boyfriend the song is directed at missed his chance, he should have proposed.
The way the words come across when I hear that lyric is somewhat different. The lyric I keep hearing are, “If you’re gonna pull my finger, put a ring on it.”
Considering what happened the last time I fell for that prank, it’s hard to fault the guy for his decision.
