Truth of Idioms

If Monkey see, Monkey do,
Then what if Monkey ate some poo?

If she eats like a bird,
Then what if birdy ate a herd?

If you shouldn't count your chickens before they hatch,
Then what if they wanted to play a tennis match?

If it's as fit a fiddle,
Then what if it danced and sang "Hey, diddle diddle?"

If it's nothing to sneeze at,
Then what if it's a smelly rat?

True, idioms, they may be.
But have you found the problem with glee?
