A subplot involves Roger renovating the Smiths' attic into a health club and attempting to pressure Steve into a long-term membership.
Klaus Heisler, the Smiths' man-in-a-fish-body pet, learns that his long lost original (human) body has been discovered and stored frozen by the CIA (Stan's place of employment).
Excited by the idea of finally being able to ski jump again and pull off his famous stunt he never got to perform, dubbed "Da Flippity Flop", Klaus begs Stan to help him retrieve the body.
However, Francine and Hayley suddenly break out in laughter and express complete amusement by the whole state of affairs, though they also let Klaus know that they want the switch to be short-lived.
His unsanitary escapades consist of smoking cigarettes, playing with dead animals, sleeping around with diseased hookers without protection, and getting high on heroin while a homeless addict takes the needle out, uses it, and puts it back in his arm.
Stan manages some air-time and pulls off Da Flippity Flop within the rotted body, which pleases Klaus.
It was the third highest rated show on Fox that night, beating out the Bob's Burgers third season finale, but losing to new episodes of The Simpsons and Family Guy.
Club gave the episode a B+ and noted: "This season finale of American Dad is a perfect example of how the show has settled into being above-average nearly every week, with the occasional ability to hit above or below that mark.
"[2] Robert H. Dawson of TV Equals gave a generally positive review, praising the silly humor, but criticizing the overuse of gross-out gags.
