I have used the phrase "crazy as a Banshee" many times as a figure of speech. I never really knew exactly what is a banshee. I was playing in the yard with my puppy, Markey-Mark and he was acting goofy and crazy and I thought, "What a banshee!" My quest led me to a scary website which actually explained that a banshee is a female spirit whose screams sound like a wild animal. I don't think I have been fair to my Markey. He doesn't scream like a wild animal, he just acts like a happy, happy puppy! So, going forward, I shall refer to my happy go lucky bouncing puppy as just that, a happy go lucky lovable but goofy puppy.
