Classic Poem

Dear Tom, I'm surprised that your verse did not jingle;
But your rhyme was not double, 'cause your sight was but single.
For, as Helsham observes, there's nothing can chime
Or fit more exact than one eye and one rhyme.
If you had not took physic, I'd pay off your bacon,
But now I'll write short, for fear you're short-taken.
Besides, Dick forbid me, and called me a fool;
For he says, short as 'tis, it will give you a stool.
