Quagmire tries to satisfy a sexual fantasy with Sonja on the floor of the gym at James Woods Regional High School while Principal Goodrich watches in "Quagmire's Quagmire". However, Quagmire discovers that the fantasy isn't all he expected it to be when he discovers that Goodrich has gone senile and he is concerned he won't be able to finish. Disgusted with Quagmire's lack of enthusiasm, the gym coach sends in Donahue to finish the job.
