I once had some song stuck in my head, and went to a coworker for help. As we all know, the only way to get a song out of your head is to replace it with another. It also helps to just unleash it on someone else. So having told her mine, she said "are you sure you want to do this? I don't fight fair."
So then I had the Slinky song stuck in my head for three days.
Lately, after trying to learn more about Love is Like Oxygen, which I thought for years was by ELO, I stumbled across this gem. Not only is it an earworm, but the 1972 pop freak scene is car-crash compelling.
So what's your worst earworm?
