Mr. and Mrs. Stewie

The episode originally aired on Fox in the United States on April 29, 2012.

In this episode, Stewie finds his perfect match, Penelope, and Peter and Quagmire decide to take their friendship to a new level after Lois buys twin beds.

They wreak havoc all over the world, destroying the Eiffel Tower and the Great Wall of China, causing India and Pakistan to conduct nuclear war with each other, and destroying Copenhagen with a tidal wave (while incorporating a Roaring Twenties theme).

Brian tries to convince him that while Stewie causes chaos as part of a grand scheme, Penelope does it just for kicks.

As Penelope plots to kill a teacher, Stewie tells her that Brian suggested they take it easy.
