German has a word for everything, like ohrwurm. Translated literally as "earworm" in English, it's the word for songs that get stuck in your head and won't go away. What earworm of a song do you most dread burrowing into your head?
Well, anybody who knows me knows that I am super-susceptible to earworms. gamethyme likes to exploit this, particularly with regards to that stupid Toys R Us jingle or the Oscar Meyer jingles. Those are probably the worst, but just about anything will get a song running through my head until either I can remember the entire song (or the entire SHOW if it's a show tune - curse of being a musical theater geek) or I blast it out of my head. I've found that the Winnie-the-Pooh song and singing Amazing Grace to the tune of the theme song from Gilligan's Island work best for getting things out. :)
