I was rooming with a good Lutheran fella from Nigeria. He and some of his friends were all dressed up in Nigerian clothing, getting ready to leave for a show-and-tell about Nigeria at a local Lutheran Church (Missouri Synod, not Evangelical). Some Jesus Freaks knocked at the door, and he stood there and very politely listened to them. Then he said, "Would you like to come in? We about to sacrifice a goat and since I listened to you I think that you should participate with us."

They left. Hurriedly. (He was a graduate of Oxford.)
