Mis-nomers

I wonder why so many cartoonists and scriptwriters assume that the majority of elephants call themselves Ellie. I suspect they’ve given no consideration to the low ratio of humans called Humie. Or cats called Cattie or Leprechauns called Leppie. It’s a sad assumption really. In my experience, elephants have far more sophisticated names like George, Herbert, and Sumitra.
Oh. There’s also a Nellie but we don’t talk about her anymore.
They probably really hate being called Ellie.
