The Gang is running a combination boxing club and (wireless) shoe-shine business. After the boxing gloves owner takes his gloves home, the gym rent is due, and with some customer service mistakes in the shoe-shine stand, the gang needs to raise money. They drum up business by spraying paint on men's shoes and cleaning them until a policeman catches them. One of the marks proves to be Jimbo Johnson, the 'price' fighter, who bails the gang out.
Next, identical twin brothers "Scrappy" and "Sissy" move into the neighborhood. Mickey tries to establish the social pecking order by fighting, but the boys keep switching places and confuse Mickey and the gang.
