You've all put together a pretty comprehensive list. I'll just add these few:
1. When someone answers and comments on the content of the (non-photo) illustration as if it were a photograph of the actual event taking place. (e.g., "You can see by the expression on Paul's face, how upset he really is at Barnabas!" or "Notice how organized Noah kept his worksite. It wasn't messy like you see at worldy construction projects, it's neat or organized like we see at our Quick Builds. We should be greatful to have an example like his to follow.")
2. I used to have a book study conductor who did the following...."Well that concludes the study for tonight. Since we finished a few minutes early, let's open our Bibles to this week's Bible reading and see how far we can get before 8:00. We'll go around the room and take turns by verse. Let's start to my left; Br. R_O?"
3. When it's an elder who has the first talk of the Service Meeting, and after making the few announcements he needs to, he says: "We have one additional announcement" and he leaves the stage to have Br. Judicial Committee walk up to the stage (along with the "stage" guy scampering behind to adjust the microphone). "Unrepentant Sinner is no long one of Jehovah's Witnesses." He then leaves the stage so that the other elder can come back up. Like a dog-and-pony show. Why can't the elder who is already up there just make the flippin' announcement?
4. Elders who spend the entire meeting walking the aisles and lobby handing out talk slips, KMs, etc., or who only ever sit in the back of the auditorium like some lifetime appointed "supervising attendant" (since the assigned attendants are back there too) even though their families are all sitting in the front.
5. Brothers that bring MONSTER briefcases to all the meetings (whether they're elders or not). What on earth do they have in there??? Even the most overworked corporate lawyers I know don't need to carry around cases that big anymore.
