I've got a jolly old hearsay: According to my parents, there was an elderly elder many decades ago (back when there was an short intermission between public talk and WT study) who announced, "We will now have a 15 minute intercourse before the WT study." Intermission + discourse = intercourse... what better way to get the blood flowin?
Also, this wasn't on stage but we had a schitzo publisher who had a weird skin condition. She would always bring some crazy kitchen utensil to scratch her back. She like to sit near the front in the middle so us kids enjoyed a good chuckle when the spatula or spaghetti dipper came out. Never accepted an invite to dinner at her place, though.
