Understatement is always the absolute best way to put forth earth-shaking ideas. Tell me what you know. Puns are for children, not groan readers. Go around the barn at high noon to avoid colloquialisms. Even IF a mixed metaphor sings, it should be derailed.
Exaggeration is a billion times worse than understatement.
Proofread carefully to see if you any words out. It shows me strait a weigh. Its rare lea ever wrong.
