Fatty's a harmless hobo. When he tries to cadge hooch and a free lunch at Ambrose Schnitz's bar, Herr Schnitz ejects him. Someone has been blowing up the taverns of people who treat penniless folks unkindly, so Schnitz's patrons play a trick on the publican, leaving a note that the place will blow up at 3 that afternoon. Schnitz thinks Fatty is the culprit. At two minutes to three, Fatty shows up with a cheese that he's bought with generous alms a swell tosses his way. Schnitz thinks the cheese is a bomb, and he runs for the cops. Fatty has the bar to himself.
