Some monks were running low on funds, but didn't want to close up their monastery. After much consideration, they decided to start selling the flowers they grew. Soon after opening up shop, business boomed, much to their delight. They had plenty of cash now for burlap and oatmeal and everything else good monks need.
Unfortunately, the town already HAD a flower shop. The disgruntled owner of the rival store tried everything -- having discount sales, spreading slander about the monks, and even poisoning the monks' flower beds. Unfortunately, they'd been blessed and nothing could stop their little business.
Finally, the rival shop owner sought out a much-rumored-of man: Hugh. No one knew his last name, just that he got the job done, no questions asked. After the appropriate amount of money had changed hands, Hugh went over to the friars' place, thoroughly beat them silly, and then destroyed their flower beds.
The next day, the monks promptly boarded up the windows and closed shop permanently, thus proving that Hugh, and only Hugh, can prevent florist friars.
