On more adversarial transactions, thoughtful lawyers should always make a point to include somewhat nastily worded “note to draft” footnotes in the document mark-ups they send to opposing counsel (e.g., “This provision has no practical value and is nonsensical. Please consult with your client on the business terms of this transaction before wasting our time with another draft” or “In violation of your duties as a member of the state bar, you appear to be unaware of recent changes in the applicable law. Please update your knowledge of the statute and revise this section accordingly.”). Usually your counterpart, annoyed by the needlessly confrontational NTD, will respond with their own, which gives you another opening to include one.  Ultimately, you want to get to a place where everyone anxiously awaits the next draft to see who will come up with the sickest legal burn.
