Housetrap

In this episode, the family gets stuck in a terrible storm while helping Teddy secure a beach house in Craggy Neck.

Teddy reveals that for extra income he sometimes aids in the maintenance of a beach house in Craggy Neck owned by a widow named Helen.

To help him out Linda offers to drive over to move the patio furniture inside so it will not be ruined in the upcoming storm.

Bob finds her charming, especially after she gives him pain relievers to aid his bad back, while Linda and Louise become paranoid and fear for the safety of their family.

Later, drugged on pain relievers, Bob tells Helen she is nice and reveals to her that Linda thinks she is a murderer.

As the rest of the family gathers around Teddy and helps him up, a drugged Bob reaches into the mud and discovers a box filled with a hammer and pulled-out nails, indicating that Helen really did murder her husband.

In his state Bob takes the box to mean that Helen, despite knowing how to do basic maintenance, hides this fact in order to continue to keep Teddy around.

This made it the fourth most watched show on Fox that night, behind Brooklyn Nine-Nine, Family Guy and The Simpsons.
