One day, Flan was not in good humour and sent a mocking note to the abbot of the monastery telling him that if his faith was worth anything, the promise would weigh as much as the beef. The abbot weighed the beef against the note of paper in front of Flan's messenger.
The piece of paper was heavier than the beef and the messenger went back
to Flan and told him what happened. Flan raced to the monastery to see
the weighing scales with his own eyes and once he did, he confessed his
sins and became a monk in the monastery. Flan lived to be a great age
and died in the monastery as an old man.
