After another successful scam, Peters and Tucker decide to become philanthropists. Once in the provincial town of Floresville, they, with the consent of local residents, open the “World University” there, and they themselves become its trustees. On September 1, a newly minted institution hospitably opens its doors to students from five states, and philanthropists enjoy their new public role for two months. At the end of October, however, it turns out that finances are running out and we need to come up with something, and soon. However, as Andy Tucker put it, "if you put philanthropy on a commercial footing, it gives a very good profit." But soon Peters, to his horror, notices in the payroll a new professor of mathematics named McCorkle with a salary of one hundred dollars a week. His indignation truly knows no bounds, and only at the cost of great efforts Andy manages to calm his friend.

Then a man appears in the town who opens a gambling house there. Students - the sons of wealthy farmers - rush there and spend hours there, scattering money in haste. Christmas holidays begin, the town is empty. At the farewell party, Peters really hoped to meet the mysterious professor of mathematics, but that wasn't there. Returning to his room, he notices that the light in Andy’s room is on. Peering into the light, Peters sees Andy and the owner of the gambling house at the table, sharing a huge pile of money. Upon seeing Jeff, Andy informs him that this is their first semester revenue. He adds that now no one should doubt that "philanthropy, put on a commercial footing, is such an art that exerts beneficence not only to the taker, but also to the giver." In conclusion, Tucker informs Peters that tomorrow morning they are leaving Floresville. Peters has nothing against. He just wants to finally meet Professor McCorkle. Tucker is ready to satisfy a friend’s request now. The professor of mathematics is none other than the owner of a gambling establishment.
