When Lois' wealthy aunt dies unexpectedly, the Griffins inherit her extravagant mansion. Although his family doesn't want to relocate, Peter is eager to enter the ranks of the upper classes and moves them onto the estate. Revenue from the sale of the Griffins' old house goes to the live-in servants, who haven't been paid in months. Caught up in the spirit of his new social standing, Peter bids ten million dollars at the Historical Society for a work of art, offering to trade his mansion for the piece. It is revealed, however, that the mansion isn't worth enough to cover the debt. Peter goes to extraordinary means to prove the house has historical significance and in the process uncovers pictures of numerous Presidents using the mansion as a 'Presidential Whorehouse'. He sells the pictures to get out of debt. A commoner once again, Peter finds that his family still loves him.
