Peter is told he has no personality and takes it to heart. He tries to create a new personality, forcing different personae including an impersonation of Humphrey Bogart as Joe (repeating the family's dinner menu "porkchops and applesauce" in a Bogart like voice). None of the impersonations go over well so Peter buys a joke book. When he tries the jokes at his party everyone knows the punchlines. While trying to keep his party afloat, Bobby and Cindy—who are on a safety drill campaign—call a surprise fire drill, forcing everyone to leave the house.
