I remember two gentlemen with similar names (Van Horn & Van der Wal) both thought they had been called on to give the prayer. This was back at a time (late 60's) when the person simply stood up from their seat and prayed without the aid of a microphone.
These two guys were at opposite sides of the seating area and although they couldn't hear each other over their own voices, those of us in the middle could hear them both.
All of us know that JW prayers are driven by a pretty strict formula, but up until that point, it had never really struck me as creepy.
--It was like listening to automatons.
