The word I’d like to talk about is one that’s called “iota.”
My mother used to say it all the time and I will “quota.”
When I was young and wanted to do something that I shouldn’t
And Mom had told me once that no, siree, I surely couldn’t,
I’d say, “But Susie’s mother let’s her, Mom! That’s just not fair!”
Mom:  “I don’t give one iota what she said.  You can’t.  You hear?”
In actuality, iota means a small amount;
The reasoning behind it was, to Mom, of no account.
If I made up excuses from atop my curly head—
Mom frowned.  “Not one iota do I believe what you just said.”
Some other ways she used the word—and these won’t make a rhyme—
Need mentioning because they’re great and from another time:
“It doesn’t make one iota of difference to me.”
“That man doesn’t have one iota of sense.”
“There’s not one iota of truth to that remark.”
And so on.  You get the drift.
A funky word, a funny word, a word that’s fun to use
I wish that we could bring it back, and so I think I choose
To make a point of saying it then tell them what it means:
That it's the same as saying, "Right!  Not in your wildest dreams."
