fergie ferg's in the house

So, I'm being mean here and might get a dreadfully catchy and somewhat bad song in your head. I have had Fergie's damn "London Bridge" song careening through my brain for days. I don't hate it or anything--I happen to kind of enjoy dirty songs about architecture, but come on. Every few minutes, I catch myself humming, "How come every time you come around, my London, London bridge wanna go down like..." I can't be singing this song at work! At this point, I would welcome "Tom's Diner" or "Jenny From the Block."
