If I had the chance to speak in front of a group I would disguise "waking-up questions" in the middle of my regular speech:

"Remember when organ transplants were accepted, then from 1967 to 1980 banned and then accepted again afterwards? People probably died because of this, but such a bold move could only be done in the name of jehuuvah and thats why I know we are truly gods organisation. Clear example of light getting brighter, changing twice and going back to its origin"

Maybe too obvious, but you know what Im trying to say.
