Language problems

Two American preachers were visiting in Germany and attended Sunday services. Since they couldn't speak German, they decided to do as the man sitting in front of them did.

A few minutes into the service the preacher from the pulpit said something and the man in front of them stood, and they stood also. The congregation burst into laughter. They then sat down when the man did.

At the end of the service, they met the pastor and found that he spoke English. They asked him why everyone laughed so much when they stood?

The pastor explained that he had announced that they would have a christening service that evening and would the father of the child please rise.
