A few years ago, I was in a skit at the CA, demonstrating to the audience how to research topics in the WT publications.
I was asked to prepare what I was going to say, and send it to the elder, handling the main talk, so he can look it over prior to the part.
A couple of days later he gives it back to me and says, "I hope you don't mind, I've changed a few things".
Nothing I had written remained in the part, he completely revamped it.
