Whenever I have a song stuck in my head, the magical power of humming the Gremlins theme song saves me. It’s the weirdest thing. The theme song doesn’t ever get stuck in my head past a couple minutes and when it goes, it takes the other song with it.
This trick doesn’t work for my flatmate Dave, so mileage may vary. Does anyone else have a similar strategy? Apparently chewing on cinnamon sticks is a folk remedy.
