Sarah mocks the institution of marriage by announcing that she and her dog, Doug, are engaged. But when Doug actually saves Sarah's life, she ceases to view the "engagement" as sarcastic. Brian and Steve discover an old pickle jar that Steve farted in 10 years ago, which sparks a renaissance in their relationship.
Sarah strives to leave a legacy by creating a popular slang word: "Ozay." While she struggles to get others interested, Brian effortlessly succeeds in the same pursuit with his word, "Dot-nose."
Sarah discovers that her father is not dead. When she and her father reconnect, they do what any father and daughter would: form a soft rock cover band. Brian spends a ridiculous amount of money on a DVD, then commits to watching it enough times that it will make itself more economical than if he'd rented it.
Sarah is oblivious to the fact that she is 9-months pregnant, assuming she's just been bloated. When she finally comprehends her situation, she realizes she may be in over her head. Steve throws his back out on the toilet, and Brian goes to save him. In doing so, he ends up in a similar predicament.
