Before he sacrifices the Goodies. he leads his congregation in a devotional song, which just happens to be a well-known rugby song. The Goodies, recognising the song, throw themselves into singing in full voice. This surprises the Reverend. When the Goodies press this temporary advantage by pretending to be Welsh, the Reverend declares that he can't kill fellow Welshmen, tells them that his church (revealed as "Welsh Druids") worships the game of rugby union, and invites the Goodies to join them. Tim declines on the basis that they are Church of England. The Reverend claims that his is the greatest religion, and Tim challenges him to prove it. This results in the "Ecclesiastical Rugby Sevens" competition, in which various teams made up from churchmen from religious groups play against each other (one of the Seven Rugby teams is made up entirely of Derek Nimmos, and the "Festival of Light" is dominated by Mary Whitehouse, who is amusingly brutal).
