GRAMMAR RULES GONE BAD

Never use a preposition to end a sentence with.
And don't start a sentence with a conjunction.
It is wrong to ever split an infinitive.
Avoid clichés like the plague. (They're really old hat.)
Also, always avoid annoying alliteration.
Be more or less specific.
Parenthetical remarks (however relevant) are (usually) unnecessary.
Understatement is always the absolute best way
to put forth earth-shaking ideas.
Go around the barn at high noon to avoid colloquialisms.
Even IF a mixed metaphor sings, it should be derailed.
