One more story that made me laugh all weekend. A friend told me this a swears up and down that it really happened. Apparently, the worst part was that when the pastor made the error he didn't even try to continue through it, but just stepped down from the podium and went and sat down in embarrassment.
Anyway, he was a stately, old preacher who got up to give the message or do the scripture reading. As he fumbled in his shirt pocket he said,
"Please turn with me to first glasses while I pull out my Peter..."
Ah, the twelve-year-old in me is doubled over once again...
