Okay kiddo, so in the olden days, there was a man called a friar who would give a speech called a sermon to a bunch of people. This was like a big talk about God and how to be a good person.
Now, there was this one friar who was very popular because he had a special way of talking. He would use really funny stories and jokes to make people laugh, and then he would use these stories to teach people about being good and doing the right thing.
Think of it like when your teacher tells you a story to help you understand something. This friar would do something similar, but he would make it really fun and entertaining so people would remember what he said.
Lots of people would come from all over just to hear this friar's sermons because they were so popular and easy to understand. And that's why he became really famous!
