For those who cannot see the picture above, please imagine this text is the most hated font of all time*:

There are certain sins
a poet learns never to commit,
whether by teaching or
simply bad experience.

Poetic sins come in many
shapes and sizes, grammatical,
typographical, metaphorical,
or just about any -al you choose.

Bad rhyme is a minefield, unable
to know slant from abject miss,
forced form a train wreck with you
at the controls, blinded by ambition.

But the cardinal sin, the one
for which there can never be 
any excuse, mortal to a poem, is
to think you can use this font.

*comic sans, of course.
