As a young preacher, my small church had limited facilities, so we held baptisms in a creek. With alligators in the area, however, that was less than ideal. Then a minister friend suggested I bring my next group of baptismal candidates to his church for a joint baptismal service. Naturally, I accepted.
The baptismal pool had a clear front so the congregation could see everything. When the baptisms were finished, curtains were drawn, and I was left alone in the pool for a moment. The building had no air conditioning, and it was quite hot. I thought how nice it would feel to take a little dip. I glided to one end, turned, and backstroked to the other end.
Hearing a riotous uproar in the church, I looked toward the congregation. The curtain was down only to the top of the glass! An astonished and amused congregation had been watching my every move. Although it was probably the best laugh that church ever had, I never was invited back to repeat the performance.
