It happened in a hall I attended during my teenage years. The brother was later declared mentally challenged though.
You know how silent the hall normally gets when after the middle song they call an elder for a "sad announcement", to the moment they finish making the announcement. In that unusual silence I heard, just inches behind my back a horrible bong bong bong bong noise . The guy actually had a bible in one hand at the moment they made the announcement, so he made his applause with one hand and the BIBLE which made that terrible noise. After applauding, he said loudly: "Bravo...Congratulations! and good job! The workers of the 11th hour are sacking the workers of the 1rst hour."(This is a literal translation, I'm' feeling too lazy to check that verse in the English bible).
I never ever forgot that moment nor those words. A total surprise! I, the goodie-2-shoes, was mortified; just wanted to vanish from my seat. I was sitting at the back of the hall, he was leaning against the back door.
In the end, his words were meaningless because he was a recent convert who climbed up the ladder in a flash. He was a reg. pioneer and a min. servant.
