I can remember several, but here are a few.
1. The brother reading about the human "organism" repeatedly mispronounced the quoted word as orgasm during a Bible highlights part.
2. The brother reading the announcements during the days of cassettes must have read that word 20 to 30 times and incorectly pronounced the word "cass-ee-yets" every friggin time. Funny but extreamly annoying at the same time.
3. One Sunday morning when I had the high honor of reading the Watchtower for the congregation the brother conducting the "discussion" had a little trouble when reading the scripture about the "congregated throng of Jehovah." You guessed it: he said the "congregated THONG of Jehovah." My head just about exploded trying to hold in the laughter and I knew I couldn't look up at ANYBODY because I wouldn't be able to handle it. I don't know how I got through the rest of that reading because it was fairly early on as well.
Anybody remember other such moments???
