Having arrived late, the church was already packed. The only pew left was the one on the front row.
So as not to make a fool of himself, he decided to pick someone out of the crowd to imitate. He chose to follow the man sitting next to him on the front pew. As they sang, the man clapped his hands, so the missionary recruit clapped too. When the man stood up to pray, the missionary recruit stood up too. When the man sat down, he sat down. When the man held the cup and bread for the Lord's Supper, he held the cup and bread.
During the preaching, the recruit didn't understand a thing. He just sat there and tried to look just like that man in the front pew.
Then the preacher said some words that he didn't understand and he saw the man next to him stand up. So he stood up too. Suddenly a hush fell over the entire congregation. A few people gasped. He looked around and saw that nobody else was standing. So he sat down.
After the service ended, the preacher stood at the door shaking the hands of those who were leaving. When the missionary recruit stretched out his hand to greet the preacher, the preacher said, in English: "I take it you don't speak Spanish."
The missionary recruit replied: "No I don't. It's that obvious?" "Well yes," said the preacher, "I announced that the Acosta family had a newborn baby boy and would the proud father please stand up."
