Half a Worm…
To paraphrase an old joke,
Q: What’s worse than an earworm in your head?
A: Half an earworm.
For those who haven’t heard the term, an “earworm” is one of those songs that gets stuck in your head and won’t leave. But it’s a lot worse when you can only remember half of it. If you remember the whole thing, it just goes round and round and round and you can try to ignore it. But if you only remember half of it, it goes round and crashes each time and attracts your attention.
And when one half of an earworm meets one half of a different earworm, well…I shudder to contemplate.
(Do I speak from present experience? Why, yes. Yes, I do.)
