Plot summary
Lois might be pregnant, and she and Hal look back at the memories of their children's births. Francis was born during Hal and Lois' wedding, Reese was born prematurely after Lois immediately pushed him out with her strength, and Malcolm was born in the front yard because Hal wasn't there to drive her to the hospital, and her car was locked. Dewey was born in the backyard in the rain since the family had to evacuate the house after Malcolm filled it with chlorine gas. Dewey, who has been listening to his parents, is happy that they are not arguing anymore, previously thinking they were getting divorced. Lois is revealed not to be pregnant after all.
