Lt-Cmdr Price's "Not Received file" which he uses to keep track of all the orders that he'd rather not obey and doesn't intend to reply to. The sender generally gets transferred, promoted, retires, or just plain gives up long before Price does. In the rare instances it doesn't work Price will send a top priority, double urgent, angry memo demanding to know why the sender hasn't responded to his questions (which he hasn't sent) about said orders. That generally shuts them up in embarrasment and he hears no more about it.

At a business meeting with a musical greeting card company Bet decided to act on this advice by climbing onto the company owner's desk and exposing himself. It paid off in the end, as the owner admired Bret's balls.
