A man is visiting a foreign country but does not speak the language that they speak there.
He decides to go to a church service, but the priest is speaking the native language, so the American man just does whatever the man in front of him does.
When the man in front of him stands, so does the American man.
When the man in front of him sits, so does the American man.
At one point, the priest says something, and the man in front of him stood.
So the American man stood too.
Everyone in the church gasped, so the American man hurriedly sat back down.
Later, the American man figured out that the priest was congratulating a birth.
When he had asked who was the father, and both men stood up, it had caused some confusion!
