A group of friars were behind on their belfry payments, so they opened up a small florist shop to raise funds. Since everyone liked to buy flowers from the men of God, they were immediately successful.
A rival florist across town thought the competition was unfair. He asked the good fathers to close down, but they would not. He went back and begged the friars to close. They ignored him.
So, the rival florist hired Hugh MacTaggart, the roughest and most vicious thug in town to "persuade" the friars to close. Hugh beat up the friars and trashed their store, saying he'd be back if they didn't close up shop. Terrified, they did so, thereby proving that only Hugh can prevent florist friars.
