“An Unsuspected Fact”

If down his throat a man should choose,
In fun, to jump or slide,
He’d scrape his shoes against his teeth,
Before he went inside.
But if his teeth were lost or gone,
And not a stump to scrape upon,
He’d see at once how very pat
His tongue lay there by way of mat,
And he would wipe his feet on that!
