At the beginning of the play, Marullus encounters a cobbler and a carpenter wandering around the streets, without the tools of their trade, celebrating. He demands to know why they are celebrating and not working, given that it isn't a holiday. The cobbler jokes that he is trying to wear his shoes and therefore give himself more work, but then he explains that the pair are making their own holiday to "rejoice in [Caesar's] triumph."
Marullus is angry, asking what great victory Caesar has won to warrant this. He knows, of course, what the pair are celebrating—he demands to know whether they do not remember Pompey, who had previously been celebrated by the citizens of Rome as he passed. Now, he says, these commoners intend to strew flowers in the street to celebrate Caesar's victory over Pompey. This is, for Marullus, an illustration of the fickleness of the common people.
