Plot (Spoiler)

Peter takes the stairs at the Pawtucket Brewery upon not wanting to take the elevator with a man who has a mutual thing in common with him. After Joe fails to rescue him and Peter accidentally sets off the fire alarm, he gets reprimanded by Bert and Sheila for him being obese enough to not make it up the stairs and the water damage that he unintentionally caused. This causes Peter to turn to Quagmire for help in losing weight. Meanwhile, Brian reads something from Lois’ creative writing club as he and Stewie suspect that Lois is having an affair with Horatio, a Stop & Shop worker, that matches the description of one of her story’s characters.
