In the US, it's considered rude to eat with your elbows on the table. Here's a rhyme to remind kids…

Notes

Another Version:

Mabel, Mabel, strong and able,
Keep your elbows off the table,
This is not a horse's stable,
But a fancy dining table.

An adaptation for the modern world:

Mabel, Mabel, strong and able,
Keep your cell phone off the table.
We've told you once,
We've told you twice,
We'll never, ever tell you thrice.
