I have heard quite a few from the platform. They used one illustration to dirtify associating with people that are not witlesses--they take a glass of clean water (the witlesses) and introduce one drop of urine (representing association with worldly people. Now, who would want that glass of water? Then, they take another glass of urine (the worldly group) and add one drop of clean water (representing a witless)--which does not make that glass fit for consumption. Later, they used the term "poison" in the same talk to represent the worldly people and their organizations.
Another illustration I heard from the platform is that a group of worldly people were trying to tempt a witless to go to the store with them, and later in the talk they mentioned that the group robbed the store. This underhandedly paints all worldly people as robbers. I also heard worldly people referred to as "dogs", "swine", and "bad association". Even people in the congregation that are not at the forefront are referred to as "vessels for a dishonorable purpose". Those come right out of the Not Well Translated Bible, and are mis-applied to refer to people that are not doing all they can to promote the Washtowel.
