At a remote monastery deep in the woods, the monks followed a rigid vow of silence. This vow could only be broken once a year on Christmas, by one monk, and he could speak only one sentence.
One Christmas, Brother Thomas had his turn to speak. He said, "I love the delightful mashed potatoes we have every year with the Christmas roast!" Then he sat down. Silence ensued for 365 days.
The next Christmas, Brother Michael got his turn. He said, "I think the mashed potatoes are lumpy and I truly despise them!" Once again, silence ensued for 365 days.
The following Christmas, Brother Paul rose and said, "I am fed up with this constant bickering!"
