Though this goes WAY back, the song katlaughing mentioned is called "New Age Girl", by Deadeye Dick.
My worst line is really not bad in and of itself, but because it is repeated at least eighty-four thousand times: Take it to the limit one more time. Every time that song gets to the end on my CD player, I cut it off. Of course, some more modern pop is considerably worse. I mean, Britney Spears "Hit me baby one more time"? Yuck.
