It's Idiomatic Poem by William Chaplar

It's sometimes automatic to say something that sounds trite.
But 'cause it's idiomatic doesn't mean it isn't right.
The English language is replete with sayings old and new.
A lot of them are hard to beat, and here are just a few.
When someone's acting too polite but isn't quite sincere,
one needn't be too erudite for it to be quite clear
that, be it east or be it west or be it north or south,
the idiom that fits him best is Butter won't melt in his mouth.
Fine character, a great big heart, and generosity;
one who would never take a part in animosity;
if in deceitful, spiteful acts you'd never be allied,
it's probably a well-known fact you're All wool and a yard wide.
If you would take a dirty slob and give him fancy clothes;
if you would read a rowdy mob Shakespearean-esque prose;
if you would us a champagne glass for chugging down moonshine,
there's some folk who would call you crass for Casting pearls before swine.
If irony is your forte and insincere you speak,
then you may spend the live-long day talking Tongue in cheek.
If you're committed to a thing and won't take any bull;
if to it, all your heart you bring, then you're Dyed in the wool.
If perfection makes you smile and mistakes cause you unease,
you likely go the extra mile to Dot i's and cross t's.
And there are hundreds more old sayings folks use every day.
And many find it quite dismaying being called cliché.
So don't dismiss the "worn out phrase" as something not worth using,
'cause saying it those other ways might be twice as confusing.
