S8, E9: When Peter gives Lois’ father the bachelor party he never had, Mr. Pewterschmidt slips into a coma and not even Dr. House can bring him out of it. With her father incapacitated, Lois is given control of Pewterschmidt Industries. Peter convinces Lois to let him run the operation, but he gets power-hungry and fires the board. Mr. Pewterschmidt soon bounces back and tries to regain control of what he’s built – even though it may be more difficult than Christmas shopping for Peter.
