Earworms are things that get into your head and you can't get them out. A VERY common earworm is a song, that gets in your head and hangs out, rent free, sometimes for months before you get it out.
Some earworms are not songs, and I offer one here. I HIGHLY recommend not telling it to your 7 year old kid, you will hear it for years, I know because that's about how old me and my siblings were when we learned it, and 50 years later, it's still in my brain when triggered. The trigger for this one is eating peas. So unless you want to hear this every time you serve your kids peas...
You have been warned.
I eat my peas with
honey, I've done it all my life.
It makes the peas taste funny, but it keeps them on the knife!
